The c.232G>C (p.G78R) alteration is located in exon 2 (coding exon 2) of the RWDD2B gene. This alteration results from a G to C substitution at nucleotide position 232, causing the glycine (G) at amino acid position 78 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
