The c.331G>C (p.G111R) alteration is located in exon 2 (coding exon 2) of the SPESP1 gene. This alteration results from a G to C substitution at nucleotide position 331, causing the glycine (G) at amino acid position 111 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
