The c.944G>A (p.G315D) alteration is located in exon 6 (coding exon 6) of the AGMAT gene. This alteration results from a G to A substitution at nucleotide position 944, causing the glycine (G) at amino acid position 315 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
