Illumina Laboratory Services, Illumina RCV001110825 SCV001268307 uncertain significance Hidrotic ectodermal dysplasia syndrome 2018-01-15 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
GeneDx RCV001759879 SCV001988370 uncertain significance not provided 2020-01-03 criteria provided, single submitter clinical testing Observed in three affected members of a nuclear family with hearing loss, and two of these individuals were also heterozygous for a variant in the GJB2 gene (Amritkumar et al., 2018); Located in the less-conserved cytoplasmic loop region of connexin 30; In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 29921236)
