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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 04, 2023In 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with SIX5-related conditions. This variant is present in population databases (rs201416246, gnomAD 0.0009%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 731 of the SIX5 protein (p.Val731Ala). -
