The c.116T>A (p.F39Y) alteration is located in exon 1 (coding exon 1) of the MTHFD2L gene. This alteration results from a T to A substitution at nucleotide position 116, causing the phenylalanine (F) at amino acid position 39 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
