Genes affected

SIX5 (HGNC:10891): (SIX homeobox 5) The protein encoded by this gene is a homeodomain-containing transcription factor that appears to function in the regulation of organogenesis. This gene is located downstream of the dystrophia myotonica-protein kinase gene. Mutations in this gene are a cause of branchiootorenal syndrome type 2. [provided by RefSeq, Jul 2009]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 721 of the SIX5 protein (p.Glu721Lys). This variant is present in population databases (rs750672211, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with SIX5-related conditions. ClinVar contains an entry for this variant (Variation ID: 1524148). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
