Illumina Clinical Services Laboratory,Illumina RCV000297256 SCV000383057 likely benign Deafness, autosomal recessive 1A 2018-01-12 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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

GeneDx RCV000080361 SCV000730583 benign not specified 2018-02-05 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

INGEBI, INGEBI / CONICET RCV001257149 SCV001433665 benign Nonsyndromic hearing loss and deafness 2020-08-31 criteria provided, single submitter clinical testing Based on ACMG/AMP guidelines and Hearing Loss Expert Panel specific criteria: the filtering allele frequency of the c.-15C>T variant in GJB2 gene is 4,86% (1271/24918 African chromosomes with 95%CI) from Genome Aggregation Database (http://gnomad.broadinstitute.org; calculated by using inverse allele frequency at https://www.cardiodb.org/allelefrequencyapp/). This is a high enough frequency, based on the thresholds defined by the ClinGen Hearing Loss Expert Panel, for autosomal recessive hearing loss variants to apply for BA1 rule. This variant is frequent (above 6%) in controls subjects from different African populations (PS4 not met, PMID: 27501294, 21392827) Benign computational verdict prediction from DANN and CADD predictors and no conservation between species (GERPscore:-5.08) applying to BP4 rule. In summary, this variant meets criteria to be classified as benign for non-syndromic hearing loss (BA1, BP4).
