Prenatal Testing for Adult-Onset Conditions: the Position of the National Society of Genetic Counselors.

Advances in genetic testing and the availability of such testing in pregnancy allows prospective parents to test their future child for adult-onset conditions. This ability raises several complex ethical issues. Prospective parents have reproductive rights to obtain information about their fetus. This information may or may not alter pregnancy management. These rights can be in conflict with the rights of the future individual, who will be denied the right to elect or decline testing. This paper highlights the complexity of these issues, details discussions that went into the National Society of Genetic Counselors (NSGC) Public Policy Task Force's development of the Prenatal testing for Adult-Onset Conditions position statement adopted in November 2014, and cites relevant literature on this topic through December 2015. Issues addressed include parental rights and autonomy, rights of the future child, the right not to know, possible adverse effects on childhood and the need for genetic counseling. This paper will serve as a reference to genetic counselors and healthcare professionals when faced with this situation in clinical practice.

Analysis of Advantages, Limitations, and Barriers of Genetic Counseling Service Delivery Models.

Previous studies on genetic counseling service delivery models (SDMs) have shown that genetic counselors (GCs) are incorporating alternate models to address growing service demand and improve access to genetic services. This study sought to identify barriers, limitations and advantages to previously identified genetic counseling SDMs. A qualitative research design was employed, in which 20 practicing GCs who utilize a variety of SDMs were interviewed using an email interview format. Interview transcripts were analyzed using a thematic analysis to identify themes related to implementation and utilization of SDMs. Factors that led GCs to implement SDMs other than in-person genetic counseling included: 1) travel distance, 2) wait time and 3) convenience. Logistical issues such as billing and reimbursement, equipment set up, making arrangements for genetic testing and the inability to see the patient are major limitations to alternative genetic counseling SDMs in clinical practice. However, GCs interviewed stated that the convenience to the patient and genetic counselor of alternative SDMs outweighed these limitations. More research is needed to assess the outcomes of SDMs in practice to demonstrate an impact on the identified barriers of travel distance, wait time and convenience.

Interventions to improve patient access to and utilisation of genetic and genomic counselling services.

This is the protocol for a review and there is no abstract. The objectives are as follows. PRIMARY OBJECTIVE: The primary objective is to assess the effectiveness of interventions to improve patient identification, access to and utilisation of genetic and genomic counselling services when compared to: No intervention;Usual or current practice; andOther active intervention. SECONDARY OBJECTIVE: The secondary objective is to explore the resource use and costs associated with interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. We will report on factors that may explain variation in the effectiveness of interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. Another secondary objective is to explore how interventions which target improved patient identification, access to and utilisation of genetic and genomic counselling services affect the subsequent appropriate use of health services for the prevention or early detection of disease. It is also possible that the genetic counselling interaction itself will contribute to the possible use of preventative services.

Outcomes of genetic evaluation for hereditary cancer syndromes in unaffected individuals.

Genetic testing (GT) for inherited cancer predisposition is most informative when initiated in individuals with cancer, thus standard practice recommends GT start in an affected individual. This strategy can be frustrating for unaffected consultands and providers. Retrospective review of cases was performed to compare outcomes of testing the unaffected consultand and recommending that testing start in an affected relative. Records from cancer-free consultands (N = 101), presenting to the University of Michigan Cancer Genetics Clinic between 6/1/2011 and 12/30/2011 were reviewed. All genetics records for these consultands were reviewed through 3/31/2013 for GT recommendations (117 total). The unaffected consultand was offered testing in 14.5 % of cases, testing was completed in 64.7 % of these with one mutation identified. Of consultands tested initially, 70.5 % received cancer-screening recommendations based on family history and test results. Testing was recommended to start in an affected family member in 30.7 % of cases. Fifty percent returned to clinic with information on an affected family member; 83.3 % documented that their family member underwent GT with one mutation identified. Consultands reported the affected family member refused testing in 22.2 % and two of these consultands subsequently pursued GT, identifying one mutation. Fifty percent of cases where testing the family member first was recommended were lost to follow-up with 66.6 % of these never given cancer-screening recommendations. Cancer genetic risk evaluation of healthy consultands should consider the option of pursuing GT in the unaffected consultand and should implement a plan for tailored risk management in the absence of informative genetic evaluation within the family.

Screening for germline mismatch repair mutations following diagnosis of sebaceous neoplasm.

IMPORTANCE Sebaceous neoplasms (SNs) define the Muir-Torre syndrome variant of Lynch syndrome (LS), which is associated with increased risk for colon and other cancers necessitating earlier and more frequent screening to reduce morbidity and mortality.Immunohistochemical (IHC) staining for mismatch repair (MMR) proteins in SNs can be used to screen for LS, but data on subsequent germline genetic testing to confirm LS diagnosis are limited.OBJECTIVE To characterize the utility of IHC screening of SNs in identification of germline MMR mutations confirming LS.DESIGN, SETTING, AND PARTICIPANTS Retrospective study at 2 academic cancer centers of 86 adult patients referred for clinical genetics evaluation after diagnosis of SN.MAIN OUTCOMES AND MEASURES Results of tumor IHC testing and germline genetic testing were reviewed to determine positive predictive value and sensitivity of IHC testing in diagnosis of LS. Clinical variables, including age at diagnosis of SN, clinical diagnostic criteria for LS and Muir-Torre syndrome, and family history characteristics were compared between mutation carriers and noncarriers.RESULTS Of 86 patients with SNs, 25 (29%) had germline MMR mutations confirming LS.Among 77 patients with IHC testing on SNs, 38 (49%) had loss of staining of 1 or more MMR proteins and 14 had germline MMR mutations. Immunohistochemical analysis correctly identified 13 of 16 MMR mutation carriers, corresponding to 81% sensitivity. Ten of 12 patients(83%) with more than 1 SN had MMR mutations. Fifty-two percent of MMR mutation carriers did not meet clinical diagnostic criteria for LS, and 11 of 25 (44%) did not meet the clinical definition of Muir-Torre syndrome. CONCLUSIONS AND RELEVANCE Immunohistochemical screening of SNs is effective in identifying patients with germline MMR mutations and can be used as a first-line test when LSis suspected. Abnormal IHC results, including absence of MSH2, are not diagnostic of LS and should be interpreted cautiously in conjunction with family history and germline genetic testing. Use of family history to select patients for IHC screening has substantial limitations,suggesting that universal IHC screening of SNs merits further study. Clinical genetics evaluation is warranted for patients with abnormal IHC test results, normal IHC test results with personal or family history of other LS-associated neoplasms, and/or multiple SNs.

Traditional roles in a non-traditional setting: genetic counseling in precision oncology.

Next generation sequencing technology is increasingly utilized in oncology with the goal of targeting therapeutics to improve response and reduce side effects. Interpretation of tumor mutations requires sequencing of paired germline DNA, raising questions about incidental germline findings. We describe our experiences as part of a research team implementing a protocol for whole genome sequencing (WGS) of tumors and paired germline DNA known as the Michigan Oncology Sequencing project (MI-ONCOSEQ) that includes options for receiving incidental germline findings. Genetic counselors (GCs) discuss options for return of results with patients during the informed consent process and document family histories. GCs also review germline findings and actively participate in the multi-disciplinary Precision Medicine Tumor Board (PMTB), providing clinical context for interpretation of germline results and making recommendations about disclosure of germline findings. GCs have encountered ethical and counseling challenges with participants, described here. Although GCs have not been traditionally involved in molecular testing of tumors, our experiences with MI-ONCOSEQ demonstrate that GCs have important applicable skills to contribute to multi-disciplinary care teams implementing precision oncology. Broader use of WGS in oncology treatment decision making and American College of Medical Genetics and Genomics (ACMG) recommendations for active interrogation of germline tissue in tumor-normal dyads suggests that GCs will have future opportunities in this area outside of research settings.

A time study of cancer genetic counselors using a genetic counselor-only patient care model versus a traditional combined genetic counselor plus medical geneticist care model.

Analyses of time-based effort have determined that clinical genetic services are labor-intensive, although these data derive primarily from studying geneticists' efforts in the pediatric model. No studies have investigated the time and patient care activities of cancer genetic counselors (GCs) in traditional clinics with a medical geneticist (GC/MD) compared with genetic counselor-only (GCO) appointments. In this study, 6 GCs prospectively tracked time spent in patient care activities in both clinical settings. The authors found that overall, GCs' time spent per patient was lower for GCO versus GC/MD visits. No differences were seen in time spent on results disclosure, but differences were noted in case preparation, face-to-face, and follow-up times. Furthermore, no differences were seen in number of case preparation activities or topics covered during a session. These data suggest that GCO visits result in better use of GCs' time, without a trade-off in number of patient-related activities.

Adrenocortical carcinoma is a lynch syndrome-associated cancer.

PURPOSE: Adrenocortical carcinoma (ACC) is an endocrine malignancy with a poor prognosis. The association of adult-onset ACC with inherited cancer predisposition syndromes is poorly understood. Our study sought to define the prevalence of Lynch syndrome (LS) among patients with ACC. PATIENTS AND METHODS: One hundred fourteen patients with ACC were evaluated in a specialized endocrine oncology clinic and were prospectively offered genetic counseling and clinical genetics risk assessment (group 1). In addition, families with known mismatch repair (MMR) gene mutations that were recorded in the University of Michigan Cancer Genetics Registry were retrospectively reviewed for the presence of ACC (group 2). ACC tumors from patients with LS were tested for microsatellite instability and immunohistochemistry (IHC) to evaluate for MMR deficiency. RESULTS: Ninety-four (82.5%) of 114 patients with ACC underwent genetic counseling (group 1). Three individuals (3.2%) had family histories suggestive of LS. All three families were found to have MMR gene mutations. Retrospective review of an additional 135 MMR gene-positive probands identified two with ACC (group 2). Four ACC tumors were available (group 1, 3; group 2, 1). All four tumors were microsatellite stable; three had IHC staining patterns consistent with germline mutation status. CONCLUSION: The prevalence of LS among patients with ACC is 3.2%, which is comparable to the prevalence of LS in colorectal and endometrial cancer. Patients with ACC and a personal or family history of LS tumors should be strongly considered for genetic risk assessment. IHC screening of all ACC tumors may be an effective strategy for identifying patients with LS.

Identification of genetic counseling service delivery models in practice: a report from the NSGC Service Delivery Model Task Force.

Increasing demand for genetic services has resulted in the need to evaluate current service delivery models (SDMs) and consider approaches that improve access to and efficiency of genetic counseling (GC). This study aimed to describe SDMs currently used by the GC community. The NSGC membership was surveyed regarding the use of four SDMs: in-person GC, telephone GC, group GC, and telegenetics GC. Variables related to access and components of use were also surveyed, including: appointment availability, time-per-patient, number of patients seen, billing, and geographic accessiblity. Seven hundred one usable responses were received. Of these, 54.7 % reported using an in-person SDM exclusively. The remainder (45.3 %) reported using multiple SDMs. Telephone, group and telegenetics GC were used often or always by 8.0 %, 3.2 % and 2.2 % of respondents, respectively. Those using an in-person SDM reported the ability to see the highest number of patients per week (p < 0.0001) and were the most likely to bill in some manner (p < 0.0001). Those using telegenetic and telephone GC served patients who lived the furthest away, with 48.3 % and 35.8 %% respectively providing GC to patients who live >4 h away. This study shows that genetic counselors are incorporating SDMs other than traditional in-person genetic counseling, and are utilizing more than one model. These adaptations show a trend toward shorter wait time and shorter length of appointments. Further study is indicated to analyze benefits and limitations of each individual model and factors influencing the choice to adopt particular models into practice.

Report from the National Society of Genetic Counselors service delivery model task force: a proposal to define models, components, and modes of referral.

The Service Delivery Model Task Force (SDMTF) was appointed in 2009 by the leadership of the National Society of Genetic Counselors (NSGC) with a charge to research and assess the capacity of all existing service delivery models to improve access to genetic counseling services in the context of increasing demand for genetic testing and counseling. In approaching this charge, the SDMTF found that there were varying interpretations of what was meant by "service delivery models" and the group held extensive discussions about current practices to arrive at consensus of proposed definitions for current genetic service delivery models, modes of referral and components of service delivery. The major goal of these proposed definitions is to allow for conversations to begin to address the charge to the committee. We propose that current models of service delivery can be defined by: 1) the methods in which genetic counseling services are delivered (In-person, Telephone, Group and Telegenetics), 2) the way they are accessed by patients (Traditional referral, Tandem, Triage, Rescue and Self-referral) and 3) the variable components that depend upon multiple factors unique to each service setting. This report by the SDMTF provides a starting point whereby standardized terminology can be used in future studies that assess the effectiveness of these described models to overcome barriers to access to genetic counseling services.

Psychological distress with direct-to-consumer genetic testing: a case report of an unexpected BRCA positive test result.

We report a case of a client who discovered she had a BRCA mutation following direct-to-consumer (DTC) genetic testing in the absence of genetic counseling. After testing she presented for genetic counseling with anxiety, distress, and a deficit of knowledge about what the DTC genetic testing revealed. Genetic counseling helped alleviate distress while empowering the client to apply the results of testing to improve medical management. Despite recent studies demonstrating no negative psychological impact of DTC genetic testing on the consumer, this case illustrates that significant psychological distress and confusion can occur as a result of DTC genetic testing for highly penetrant single gene disorders. Pre- and post-test genetic counseling in conjunction with DTC genetic testing may alleviate consumers' distress and empower clients to proactively utilize their result information.

A large health system's approach to utilization of the genetic counselor CPT® 96040 code.

PURPOSE: : In 2007, CPT® code 96040 was approved for genetic counseling services provided by nonphysician providers. Because of professional recognition and licensure limitations, experiences in direct billing by genetic counselors for these services are limited. A minority of genetics clinics report using this code because of limitations, including perceived denial of the code and confusion regarding compliant use of this code. We present results of our approach to 96040 billing for genetic counseling services under a supervising physicians National Provider ID number in a strategy for integration of genetics services within nongenetics specialty departments of a large academic medical center. METHODS: : The 96040 billing encounters were tracked for a 14-month period and analyzed for reimbursement by private payers. Association of denial by diagnosis code or specialty of genetics service was statistically analyzed. Descriptive data regarding appointment availability are also summarized. RESULTS: : Of 350 encounters January 2008 to February 2009, 289 (82%) were billed to private payers. Of these, 62.6% received some level of reimbursement. No association was seen for denial when analyzed by the diagnosis code or by genetics focus. Through this model, genetics appointment availability minimally doubled. CONCLUSION: : Using 96040 allowed for expanding access to genetics services, increased appointment availability, and was successful in obtaining reimbursement for more than half of encounters billed.

Cowden syndrome.

Cowden syndrome (CS), due to germline mutations of the PTEN tumor-suppressor gene, is an often overlooked cancer predisposition syndrome associated with an increased risk of breast, thyroid, and endometrial cancers, as well as benign manifestations. Germline PTEN mutations also are associated with syndromes that have not been historically connected to an increase in risk for malignancy. These disorders include Bannayan-Riley-Ruvalcaba syndrome (BRRS), Proteus syndrome (PS), and Proteus-like syndrome (PSL). These syndromes can be described under the umbrella of PTEN hamartoma tumor syndrome (PHTS). As one would expect in allelic disorders, there is broad phenotypic overlap in the PHTS; however, the syndromes are clinically distinct. As additional information is discovered about new syndromes of cancer predisposition and their concordant genes, oncologists and allied healthcare providers must maintain vigilance to appropriately identify, and screen, individuals at an increased risk. Although CS is the only PHTS with a clearly documented predisposition to malignancies, pending further data, for precautionary reasons all individuals with a germline PTEN mutation are recommended to follow the cancer surveillance recommendations for CS.

Health beliefs among African American women regarding genetic testing and counseling for sickle cell disease.

PURPOSE: The Health Belief Model can help in understanding low acceptance of disease prevention and screening. We studied health beliefs of African American women to determine causes of low acceptance of genetic testing and counseling despite high prevalence of sickle cell disease and heterozygotes in this population. METHODS: An anonymous questionnaire using a 12-question measure with a 5-point Likert scale response was administered to 101 African American women attending an obstetrics and gynecology clinic to determine knowledge of sickle cell disease, perception of risk, severity, likelihood of benefit and barriers to counseling. RESULTS: The cumulative mean perceived scores on the 5-point Likert scale were 4.22 +/- 0.88 for severity of sickle cell disease, 4.10 +/- 1.03 for benefit of genetic testing, 2.28 +/- 1.00 for barriers to testing, and 2.62 +/- 1.06 for risk of having a child with sickle cell disease. High average level knowledge was associated with high perception of severity and benefit to screening (P < 0.05). CONCLUSION: African American women have a relatively high belief of the severity of sickle cell disease and benefits of genetic counseling but frequently do not appear to believe that they are at risk of having a child with the disease. This should be taken into account in the design of educational and counseling strategies.
