Genes affected

DMRT2 (HGNC:2935): (doublesex and mab-3 related transcription factor 2) The protein encoded by this gene belongs to the DMRT gene family, sharing a DM DNA-binding domain with Drosophila 'doublesex' (dsx) and C. elegans mab3, genes involved in sex determination in these organisms. Also, this gene is located in a region of the human genome (chromosome 9p24.3) associated with gonadal dysgenesis and XY sex reversal. Hence this gene is one of the candidates for sex-determining gene(s) on chr 9. [provided by RefSeq, Apr 2010]

This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 6 of the DMRT2 protein (p.Ala6Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DMRT2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
