The c.43A>G (p.T15A) alteration is located in exon 2 (coding exon 1) of the DMRTA2 gene. This alteration results from a A to G substitution at nucleotide position 43, causing the threonine (T) at amino acid position 15 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
