ABSTRACT
Opportunities for genetic counselors to work in a variety of practice settings have greatly expanded, particularly in the laboratory. This study aimed to assess attitudes of genetic counselors working both within and outside of the laboratory setting regarding (1) the re-wording and/or expansion of key measures of genetic counselors' competency, including practice-based competencies (PBCs) and board examination, to include laboratory roles, (2) preparation and transferability of competencies developed in master's in genetic counseling (MGC) programs to different roles, (3) need of additional training for genetic counselors to practice in laboratory settings, and (4) preferred methods to obtain that training. An e-blast was sent to ABGC diplomats (N = 5458) with a link to a 29-item survey with 12 demographic questions to compare respondents to 2021 NSGC Professional Status Survey (PSS) respondents. Statistical comparisons were made between respondents working in the laboratory versus other settings. Among 399 responses received, there was an oversampling of respondents working in the laboratory (52% vs. 20% in PSS) and in non-direct patient care positions (47% vs. 25% in PSS). Most respondents agreed the PBCs were transferable to their work yet favored making the PBCs less direct patient care-focused, expanding PBCs to align with laboratory roles, adding laboratory-focused questions to the ABGC exam, and adding laboratory-focused training in MGC programs. Most agreed requiring post-MGC training would limit genetic counselors' ability to change jobs. Genetic counselors working in the laboratory reported being significantly less prepared by their MGC program for some roles (p < 0.001) or how the PBCs applied to non-direct patient care positions (p < 0.001). Only 53% of all respondents agreed that NSGC supports their professional needs and others in their practice area, and genetic counselors working in the laboratory were significantly less likely to agree (p = 0.002). These sentiments should be further explored.
ABSTRACT
Cells are regularly exposed to a range of naturally occurring stress that can restrict growth or cause lethality. In response, cells activate expression networks with hundreds of genes that together increase resistance to common environmental insults. However, stress response networks can be insufficient to ensure survival, which raises the question of whether cells possess genetic programs that can promote adaptation to novel forms of stress. We found transposable element (TE) mobility in Schizosaccharomyces pombe was greatly increased when cells were exposed to unusual forms of stress such as heavy metals, caffeine, and the plasticizer phthalate. By subjecting TE-tagged cells to CoCl2, we found the TE integration provided the major path to resistance. Groups of insertions that provided resistance were linked to TOR regulation and metal response genes. We extended our study of adaptation by analyzing TE positions in 57 genetically distinct wild strains. The genomic positions of 1048 polymorphic LTRs were strongly associated with a range of stress response genes, indicating TE integration promotes adaptation in natural conditions. These data provide strong support for the idea, first proposed by Barbara McClintock, that TEs provide a system to modify the genome in response to stress.
