The c.1516A>C (p.S506R) alteration is located in exon 3 (coding exon 2) of the DMRTA2 gene. This alteration results from a A to C substitution at nucleotide position 1516, causing the serine (S) at amino acid position 506 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
