The c.142G>A (p.V48I) 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 142, causing the valine (V) at amino acid position 48 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
