The c.1294G>A (p.G432R) alteration is located in exon 5 (coding exon 5) of the ANGEL1 gene. This alteration results from a G to A substitution at nucleotide position 1294, causing the glycine (G) at amino acid position 432 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
