The c.121G>A (p.V41M) alteration is located in exon 2 (coding exon 1) of the MFAP3L gene. This alteration results from a G to A substitution at nucleotide position 121, causing the valine (V) at amino acid position 41 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
