The c.331G>A (p.G111S) alteration is located in exon 1 (coding exon 1) of the GALNT15 gene. This alteration results from a G to A substitution at nucleotide position 331, causing the glycine (G) at amino acid position 111 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
