Ambry Genetics

Feb 14, 2023

The c.931G>A (p.G311R) alteration is located in exon 8 (coding exon 8) of the MTHFSD gene. This alteration results from a G to A substitution at nucleotide position 931, causing the glycine (G) at amino acid position 311 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
