Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004788568 SCV005398907 uncertain significance Hearing loss, autosomal dominant 78 2023-07-16 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3C. Following criteria are met: 0103 - Dominant negative and loss of function and gain of function are mechanisms of disease in this gene and are associated with Deafness 78 (MIM#619081), Delpire-McNeill syndrome (MIM#619083), Kilquist syndrome (MIM#619080). Dominant negative or gain of function are suggested mechanisms for missense variants that are associated with dominant deafness, whereas biallelic mutations usually result in a loss of function effect (PMID: 30740830, 32754646, 32294086, 34226616). (I) 0108 - This gene is associated with both recessive and dominant disease. Autosomal dominant is the predominant mode of inheritance whereas biallelic mutations lead to recessive condition (PMID: 34226616). (I) 0200 - Variant is predicted to result in a missense amino acid change from isoleucine to valine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2 and v3) <0.01 (2 heterozygotes, 0 homozygotes). (SP) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0600 - Variant is located in the annotated SLC12 domain (DECIPHER). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
