(Wiley, 2020-07-15)Childhood dilated cardiomyopathy (DCM) is a leading cause of heart failure requiring cardiac transplantation and approximately 5% of cases result in sudden death. Knowledge of the underlying genetic cause can aid prognostication ... -
UKCGG Consensus Group guidelines for the management of patients with constitutional TP53 pathogenic variants
(BMJ, 2020-06-22)Constitutional pathogenic variants in TP53 are associated with Li-Fraumeni syndrome or the more recently described heritable TP53-related cancer syndrome and are associated with increased lifetime risks of a wide spectrum ... -
Prostate Cancer Risk by BRCA2 Genomic Regions
(Elsevier Science, 2020-10)A BRCA2 prostate cancer cluster region (PCCR) was recently proposed (c.7914 to 3') wherein pathogenic variants (PVs) are associated with higher prostate cancer (PCa) risk than PVs elsewhere in the BRCA2 gene. Using a ... -
Late-onset Pseudoxanthoma Elasticum Associated with a Hypomorphic ABCC6 Variant
(Elsevier Science, 2020-10)Purpose: To describe patients with late-onset pseudoxanthoma elasticum (PXE) associated with a likely hypomorphic ABCC6 variant. Design: Retrospective observational case series. Methods: Clinical evaluation, multimodal ... -
Phenotypic expansion of Bosch-Boonstra-Schaaf optic atrophy syndrome and further evidence for genotype-phenotype correlations
(Wiley, 2020-06)Bosch-Boonstra-Schaaf Optic Atrophy Syndrome (BBSOAS) is an autosomal dominant neurodevelopmental disorder caused by loss-of-function variants in NR2F1 and characterized by visual impairment, developmental delay, and ... -
Primrose syndrome: Characterization of the phenotype in 42 patients
(Wiley, 2020-06)Primrose syndrome (PS; MIM# 259050) is characterized by intellectual disability (ID), macrocephaly, unusual facial features (frontal bossing, deeply set eyes, down-slanting palpebral fissures), calcified external ears, ... -
Novel truncating mutations in CTNND1 cause a dominant craniofacial and cardiac syndrome
(Oxford University Press, 2020-07-21)CTNND1 encodes the p120-catenin (p120) protein, which has a wide range of functions, including the maintenance of cell-cell junctions, regulation of the epithelial-mesenchymal transition and transcriptional signalling. Due ... -
Clinical spectrum of POLR3-related leukodystrophy caused by biallelic POLR1C pathogenic variants
(Wolters Kluwer Health, 2019-10-30)Objective: To determine the clinical, radiologic, and molecular characteristics of RNA polymerase III-related leukodystrophy (POLR3-HLD) caused by biallelic POLR1C pathogenic variants. Methods: A cross-sectional observational ... -
Dominant mutations of the Notch ligand Jagged1 cause peripheral neuropathy
(American Society for Clinical Investigation, 2020-03-02)Notch signaling is a highly conserved intercellular pathway with tightly regulated and pleiotropic roles in normal tissue development and homeostasis. Dysregulated Notch signaling has also been implicated in human disease, ... -
Opposite Modulation of RAC1 by Mutations in TRIO Is Associated with Distinct, Domain-Specific Neurodevelopmental Disorders
(Elsevier Science, 2020-03-05)The Rho-guanine nucleotide exchange factor (RhoGEF) TRIO acts as a key regulator of neuronal migration, axonal outgrowth, axon guidance, and synaptogenesis by activating the GTPase RAC1 and modulating actin cytoskeleton ... -
Recurrent De Novo NAHR Reciprocal Duplications in the ATAD3 Gene Cluster Cause a Neurogenetic Trait with Perturbed Cholesterol and Mitochondrial Metabolism
(Elsevier Science, 2020-02-06)Recent studies have identified both recessive and dominant forms of mitochondrial disease that result from ATAD3A variants. The recessive form includes subjects with biallelic deletions mediated by non-allelic homologous ... -
