The c.137G>T (p.G46V) alteration is located in exon 6 (coding exon 2) of the RPA3 gene. This alteration results from a G to T substitution at nucleotide position 137, causing the glycine (G) at amino acid position 46 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
