Labcorp Genetics (formerly Invitae), Labcorp RCV002027546 SCV002308558 likely pathogenic Branchiootic syndrome 3; Autosomal dominant nonsyndromic hearing loss 23 2022-04-01 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Arg110 amino acid residue in SIX1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15141091, 24164807). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This missense change has been observed in individual(s) with clinical features of branchiootorenal spectrum conditions (Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 110 of the SIX1 protein (p.Arg110Leu).
