The c.3273A>C (p.R1091S) alteration is located in exon 2 (coding exon 2) of the RAD51AP2 gene. This alteration results from a A to C substitution at nucleotide position 3273, causing the arginine (R) at amino acid position 1091 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
