The c.358G>A (p.V120I) alteration is located in exon 4 (coding exon 4) of the FAIM2 gene. This alteration results from a G to A substitution at nucleotide position 358, causing the valine (V) at amino acid position 120 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
