The c.1303G>C (p.A435P) alteration is located in exon 13 (coding exon 13) of the R3HDM2 gene. This alteration results from a G to C substitution at nucleotide position 1303, causing the alanine (A) at amino acid position 435 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
