The c.1126G>A (p.D376N) alteration is located in exon 5 (coding exon 5) of the GPATCH3 gene. This alteration results from a G to A substitution at nucleotide position 1126, causing the aspartic acid (D) at amino acid position 376 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
