The c.448A>G (p.M150V) alteration is located in exon 2 (coding exon 2) of the C2CD2L gene. This alteration results from a A to G substitution at nucleotide position 448, causing the methionine (M) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
