The c.344A>G (p.K115R) alteration is located in exon 3 (coding exon 2) of the DMRTC2 gene. This alteration results from a A to G substitution at nucleotide position 344, causing the lysine (K) at amino acid position 115 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
