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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 11, 2024The c.143A>C (p.D48A) alteration is located in exon 2 (coding exon 1) of the DMRT2 gene. This alteration results from a A to C substitution at nucleotide position 143, causing the aspartic acid (D) at amino acid position 48 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
