ABSTRACT

BACKGROUND: The heterogeneity of nasal features across different ethnical groups is evident. This large-scale multicenter study evaluates dorsal keystone area and its relation to superficial nasal anatomy, through computed tomography (CT) scans. METHODS: Six different populations were included: South Caucasian, Middle Eastern, Black South African, Eastern Asian, Mestizo and Eastern European. Each center obtained CT scans performed between January 2020 and December 2022 from patients presenting a nasal hump and from an age and sex-matched control group. Osteocartilaginous measurements in relation to Ethmoidal-point and to Rhinion, as well as their relation to superficial nasal anatomy, were collected from nasal CT scans in midsagittal view. These were compared between populations and, in each center, compared between patient groups (nasal hump versus no nasal hump). RESULTS: The study population included 600 patients (254 with nasal hump), with a mean age of 33.98 (ranging 18 - 59) years old, and 55.6% were female. The distance from the Ethmoidal-point averaged: to Rhinion 10.1(±3.5)mm; and to nasal hump beginning point 1.68 (±0.23)mm. In 96% of cases the Ethmoidal-point was cranial or no more than 5mm caudal to the beginning of the nasal hump. S-shaped nasal bones were associated with nasal hump but its angulation (kyphion angle) did not correlate with nasal hump height. CONCLUSIONS: In most patients, the nasal hump has no ethmoid bone underneath it, and it apex is located over the septal cartilage. The Ethmoidal-point is a reliable landmark and should be considered when appreciating established and new preservation and structural rhinoplasty approaches.

ABSTRACT

This study reports a green, simple, and fast method for the synthesis of gold and silver nanoparticles using natural antioxidant compounds. The aqueous extract from dried rosehips (pseudofruit of Rosa canina L.) was used as a reducing and capping agent of HAuCl4 and AgNO3 during the noble metal colloid synthesis at room temperature and no other chemical reagent was used. The high antioxidant activity of the plant extract was proven by 2,2-diphenyl-1-picrylhydrazyl assay by a spectrophotometric method. The formation of stable gold and silver nanoparticles was observed by UV-visible spectroscopy and the evolution of their characteristic surface plasmon resonance band was followed over several days. Transmission electron microscopy confirmed the formation of quasi-spherical nanoparticles with mean diameters 26 and 34 nm, for gold and silver nanoparticles, respectively; XRD revealed an FCC crystalline structure for both gold and silver NPs. The effects of concentrations of noble metal precursor and plant extract solution on the formation, stabilization and size of nanoparticles are discussed, as well as some applications of these colloids.

ABSTRACT

El síndrome de Sjogren-Larsson se caracteriza por retardo mental, ictiosis congènita y diplejía o cuadriplejía espástica. El defecto primario en este síndrome es la mutación del gen ALDH3A2, que codifica la enzima aldehído deshidrogenasa grasa y causa una deficiencia enzimática que produce una acumulación de alcoholes y aldehídos grasos en los tejidos que comprometen la integridad de la membrana celular, cuyos efectos pueden observarse en la piel, los ojos y el sistema nervioso central. El diagnóstico se realiza por medio de la cuantificación de la actividad de la enzima. Se describe el caso de una paciente con signos clínicos patognomónicos del síndrome de Sjogren-Larsson, cuyo diagnóstico se realizó por medio de la cuantificación de la actividad enzimática en un cultivo de fibroblastos. Además, tomando en cuenta el árbol genealógico de la paciente, se realizó el estudio en los padres y un hermano con signos sugestivos del síndrome de Sjogren-Larsson.


Sjogren-Larsson syndrome is characterized by congenital ichthyosis, mental retardation and spastic diplegia or quadriplegia. The primary defect in this syndrome is mutation of ALDH3A2 gen that codes for the fatty aldehyde dehydrogenase. Deficiency of this enzyme causes an accumulation of fatty alcohols and fatty aldehydes, leading to altered cell-membrane integrity. Skin, eyes, and the central nervous system are affected latter. The diagnosis is carried out through the cuantification of the enzyme activity.

ABSTRACT

Craniosynostosis is commonly caused by mutations in fibroblast growth factor receptors (FGFRs), highlighting the essential role of FGF-mediated signaling in skeletal development. We set out to identify the molecular defect in a family referred for craniosynostosis and in whom no mutation was previously detected. Using next-generation sequencing, we identified a novel missense mutation in FGF9. Modeling based upon the crystal structure and functional studies confirmed its pathogenicity showing that it impaired homodimerization and FGFR3 binding. Only one FGF9 mutation has been previously reported in a multigeneration family with multiple synostoses (SYNS3) but no signs of craniosynostosis. In contrast, our family has a greater phenotypic resemblance to that observed in the Fgf9 spontaneous mouse mutant, elbow-knee-synostosis, Eks, with both multiple synostoses and craniosynostosis. We have demonstrated for the first time that mutations in FGF9 cause craniosynostosis in humans and confirm that FGF9 mutations cause multiple synostoses.

ABSTRACT

Interstitial deletions in the short arm of chromosome 1 are infrequent. We report a female with a 1p31.1p31.3 deletion and cloverleaf skull, who presented with renal and central nervous system malformations, cleft palate, severe ocular anomalies, and cutis laxa, in addition to the previously described clinical data present in other cases with deletions encompassing this region, such as developmental delay, seizures, round face with a prominent nose, micro/retrognathia, half-opened mouth, short neck, hand/foot malformations, hernia, congenital heart malformations, and abnormal external genitalia. The deletion spanned ∼18.6 Mb and included a total of 68 OMIM protein coding genes. We have reviewed 17 cases previously described in the literature and in DECIPHER involving the chromosomal region 1p31.1p31.3. Only 3 of these affect the whole region, 9 are partial deletions of this region, and 5 are much smaller deletions. Taking into account the MORBID ID and the haploinsufficiency score of the genes, we go on to propose which genes may explain particular clinical features observed in the patient. IL23R may be responsible for the craniosynostosis, FOXD2 for the renal anomalies, LHX8 for closure defects of the palate, and ST6GALNAC3 for skin anomalies. In summary, we have identified a chromosome 1p31.1p31.3 deletion in a patient with an atypical presentation of craniosynostosis amongst other more typical features observed in individuals with similar deletions.

ABSTRACT

Schimke immunoosseous dysplasia (SIOD) is an autosomal recessive disease characterized by skeletal dysplasia, focal segmental glomerulosclerosis, renal failure and immunodeficiency. In this work, we report the molecular studies undertaken in a severely affected SIOD patient that died at six years old due to nephropathy. The patient was screened for mutations using a targeted skeletal dysplasias panel. A homozygous novel missense mutation was identified, c.1615C > G (p.[Leu539Val]) that was predicted as mildly pathogenic by in silico pathogenicity prediction tools. However, splicing prediction software suggested that this variant may create a new splicing donor site in exon 9, which was subsequently confirmed using a minigene assay in HEK293 cells. Thus, the splicing alteration, c.1615C > G; r.1615c > g, 1615_1644del; (p.[Leu539_Ile548del]), results in the loss of 10 amino acids of the HARP-ATPase catalytic domain and the RPA-binding domain. Several studies have demonstrated a weak genotype-phenotype correlation among such patients. Thus, the molecular characterization has helped us to understand why a predicted weakly pathogenic missense mutation results in severe SIOD and should be considered in similar scenarios.

ABSTRACT

Progressive pseudorheumatoid dysplasia (PPD) is a rare autosomal recessive disorder characterized by spondyloepiphyseal dysplasia associated with pain and stiffness of multiple joints, enlargement of the interphalangeal joints, normal inflammatory parameters, and absence of extra-skeletal manifestations. Homozygous or compound heterozygous WISP3 mutations cause PPD. We report two siblings from a non-consanguineous Ecuadorian family with a late-onset spondyloepiphyseal dysplasia. Mutation screening was undertaken in the two affected siblings using a customized skeletal dysplasia next generation sequencing (NGS) panel and confirmed by Sanger sequencing. Two compound heterozygous mutations were identified in WISP3 exon 2, c.[190G>A];[197G>A] (p.[(Gly64Arg)];[(Ser66Asn)]) in the two siblings, both of which had been inherited. The p. (Gly64Arg) mutation has not been previously described whilst the p. (Ser66Asn) mutation has been reported in two PPD families. The two siblings presented with atypical PPD, as they presented during late childhood, yet the severity was different between them. The progression was particularly aggressive in the male sibling who suffered severe scoliosis by the age of 13 years. This case reaffirms the clinical heterogeneity of this disorder and the clinical utility of NGS to genetically diagnose skeletal dysplasias, enabling adequate management, monitorization, and genetic counseling. © 2016 Wiley Periodicals, Inc.

ABSTRACT

Primordial dwarfism encompasses rare conditions characterized by severe intrauterine growth retardation and growth deficiency throughout life. Recently, three POC1A mutations have been reported in six families with the primordial dwarfism, SOFT syndrome (Short stature, Onychodysplasia, Facial dysmorphism, and hypoTrichosis). Using a custom-designed Next-generation sequencing skeletal dysplasia panel, we have identified two novel homozygous POC1A mutations in two individuals with primordial dwarfism. The severe growth retardation and the facial profiles are strikingly similar between our patients and those described previously. However, one of our patients was diagnosed with severe foramen magnum stenosis and subglottic tracheal stenosis, malformations not previously associated with this syndrome. Our findings confirm that POC1A mutations cause SOFT syndrome and that mutations in this gene should be considered in patients with severe pre- and postnatal short stature, symmetric shortening of long bones, triangular facies, sparse hair and short, thickened distal phalanges.

ABSTRACT

Craniosynostosis, caused by the premature fusion of one or more of the cranial sutures, can be classified into non-syndromic or syndromic and by which sutures are affected. Clinical assignment is a difficult challenge due to the high phenotypic variability observed between syndromes. During routine diagnostics, we screened 182 Spanish craniosynostosis probands, implementing a four-tiered cascade screening of FGFR2, FGFR3, FGFR1, TWIST1 and EFNB1. A total of 43 variants, eight novel, were identified in 113 (62%) patients: 104 (92%) detected in level 1; eight (7%) in level 2 and one (1%) in level 3. We subsequently screened additional genes in the probands with no detected mutation: one duplication of the IHH regulatory region was identified in a patient with craniosynostosis Philadelphia type and five variants, four novel, were identified in the recently described TCF12, in probands with coronal or multisuture affectation. In the 19 Saethre-Chotzen syndrome (SCS) individuals in whom a variant was detected, 15 (79%) carried a TWIST1 variant, whereas four (21%) had a TCF12 variant. Thus, we propose that TCF12 screening should be included for TWIST1 negative SCS patients and in patients where the coronal suture is affected. In summary, a molecular diagnosis was obtained in a total of 119/182 patients (65%), allowing the correct craniosynostosis syndrome classification, aiding genetic counselling and in some cases provided a better planning on how and when surgical intervention should take place and, subsequently the appropriate clinical follow up.

ABSTRACT

El síndrome de Adams Oliver (AOS) es una entidad heterogénea con defecto transverso terminal de extremidades (TTLD) y aplasia cutis congénita (ACC) con un amplio espectro fenotípico. Se han descrito diferentes modos de herencia en esta enfermedad; los defectos más graves se han asociado a un patrón autosómico recesivo (AR). Objetivo. presentar a una familia con dos medio hermanas con un fenotipo grave de Adams Oliver, con una madre sana. Reporte del caso: una mujer de 27 años de edad fue referida al Departamento de Genética. Su hija anterior presentó acránea, anillos de constricción y defectos transversos terminales de extremidades. Su hija actual presentaba encefalocele occipital, defecto amplio en huesos del cráneo, aplasia cutis congénita, defecto terminal transverso de extremidades y labio y paladar hendido bilateral. Sugerimos que algunos casos con fenotipo grave del síndrome de Adams Oliver pueden deberse a herencia autosómico dominante con penetrancia incompleta o a la presencia de mosaicismo gonadal.


Adams Oliver syndrome (AOS) is a highly variable entity with terminal transverse limb defects (TTLD) and aplasia cutis congenita (ACC) with a wide phenotypic spectrum. Several inheritance models have been observed; the most severe phenotype has been related to an autosomal recessive (AR) pattern of inheritance. Objective. To present a family with two half siblings with a severe phenotype of Adams Oliver syndrome in which the mother was healthy. Case report: A 27 year-old woman was referred to the Genetics Department. Her previous girl presented acrania, constriction rings and terminal transverse limb defects. The present girl had occipital encephalocele, large scalp defects, aplasia cutis congenita, terminal transverse limb defects and bilateral cleft lip and palate. Autosomal dominant inheritance with reduced penetrance or gonadal mosaicism has to be considered in Adams Oliver syndrome with severe intracranial anomalies.

ABSTRACT

Introducción: El MLPA (amplificación de sondas dependiente de ligandos múltiples) es un método reciente, basado en la reacción en cadena de la polimerasa (RCP), de cuantificación relativa del número de copias normales y anormales de ácido desoxirribonucleico (ADN) de hasta 40 secuencias genómicas diferentes. Su uso se ha difundido tanto en la investigación como en el diagnóstico clínico. Recientemente, el MLPA se ha utilizado en diagnóstico prenatal y en el estudio de abortos. Objetivo: Presentar los primeros resultados obtenidos con MLPA en el diagnóstico perinatal de las principales aneuploidías de los cromosomas 13, 18, 21, X y Y. Material y métodos: Se obtuvo ácido desoxirribonucleico genómico de tejidos sin cultivar de aborto, biopsia de vellosidades coriales (VC), líquido amniótico (LA), cordón umbilical (CU) de óbitos o sangre periférica (SP) de recién nacidos, en 13 casos con patología perinatal. Para el MLPA se utilizó el kit p 290 para diagnóstico prenatal y sus productos se cuantificaron en un secuenciador ABI Prism 3130. Todos los casos se procesaron para cariotipo en forma paralela. Resultados: Se obtuvieron resultados con MLPA entre dos y tres días en las 13 muestras estudiadas. Seis de ellas mostraron aneuploidías. El cariotipo se obtuvo entre 15 y 21 días en 11 casos, cinco fueron aneuploides y dos fallaron. Los resultados entre MLPA y cariotipo fueron concordantes en las fallas del cultivo celular, el diagnóstico se obtuvo por MLPA. Conclusiones: El MLPA es un método útil y rápido en el diagnóstico perinatal de las principales aneuploidías; además, tiene la ventaja de permitir estudiar tejidos con baja viabilidad celular como ocurre en algunos casos de aborto u óbito.


Introduction: The MLPA (multiplex ligation-dependent probe amplification) is a new method based on polimerase chain reaction (PCR) for relative quantification of normal and abnormal numbers of copies of desoxyribonucleic (DNA), up to 40 different genomic sequences. Its use is widespread in both, research and clinical diagnosis. MLPA recently began to be used in prenatal diagnosis and study of pregnancy losses. Objective: Present the first results obtained with MLPA in perinatal diagnosis of major aneuploidies of chromosomes 13, 18, 21, X and Y. Methods: Genomic DNA was obtained from different uncultivated tissues: abortion, chorionic villus, amniotic fluid, umbilical cord blood or peripheral blood in 13 cases with perinatal pathology. MLPA kit p290 for prenatal diagnosis was used and its products were quantified in ABI Prism 3130 sequencer. All cases were processed in parallel for karyotype. Results: MLPA results were obtained in 2 to 3 days in the 13 samples studied. Six of them showed aneuploidy. Karyotype was obtained between 15 and 21 days in 11 cases, five were aneuploidy and two failed. The results obtained with MLPA and karyotypes were concordant and in cases where the cell culture failed, the diagnosis was obtained by MLPA. Conclusions: MLPA is a rapid and useful method in the perinatal diagnosis of major aneuploidies, it also has the advantage of allowing the study of tissues with low cell viability, as in some cases of abortion and fetal death.
