The c.151G>A (p.G51R) alteration is located in exon 2 (coding exon 2) of the GPATCH1 gene. This alteration results from a G to A substitution at nucleotide position 151, causing the glycine (G) at amino acid position 51 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
