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 threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 552 of the SIX5 protein (p.Thr552Met). This variant is present in population databases (rs80356464, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with branchio-oto-renal syndrome (PMID: 17357085, 24429398). ClinVar contains an entry for this variant (Variation ID: 8601). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SIX5 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects SIX5 function (PMID: 17357085). 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. -
