The c.605A>T (p.D202V) alteration is located in exon 7 (coding exon 7) of the MTHFSD gene. This alteration results from a A to T substitution at nucleotide position 605, causing the aspartic acid (D) at amino acid position 202 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
