The c.689A>C (p.D230A) alteration is located in exon 5 (coding exon 5) of the MTHFD2L gene. This alteration results from a A to C substitution at nucleotide position 689, causing the aspartic acid (D) at amino acid position 230 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
