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]

The c.2177C>G (p.T726S) alteration is located in exon 3 (coding exon 3) of the SIX5 gene. This alteration results from a C to G substitution at nucleotide position 2177, causing the threonine (T) at amino acid position 726 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
