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 serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 730 of the SIX5 protein (p.Ser730Leu). This variant is present in population databases (rs150045306, gnomAD 0.01%). This missense change has been observed in individual(s) with bilateral kidney agenesis (PMID: 28566479). ClinVar contains an entry for this variant (Variation ID: 1315723). 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. 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. -
