The c.169G>C (p.G57R) alteration is located in exon 2 (coding exon 2) of the RBM48 gene. This alteration results from a G to C substitution at nucleotide position 169, causing the glycine (G) at amino acid position 57 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
