The c.949A>G (p.I317V) alteration is located in exon 3 (coding exon 2) of the MFAP3L gene. This alteration results from a A to G substitution at nucleotide position 949, causing the isoleucine (I) at amino acid position 317 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
