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 submitter	clinical testing	CeGaT Center for Human Genetics Tuebingen	Sep 01, 2022	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Nov 13, 2023	This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 700 of the SIX5 protein (p.Asp700Asn). This variant is present in population databases (rs374469828, gnomAD 0.01%). 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: 1992099). 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. -

The c.2098G>A (p.D700N) alteration is located in exon 3 (coding exon 3) of the SIX5 gene. This alteration results from a G to A substitution at nucleotide position 2098, causing the aspartic acid (D) at amino acid position 700 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
