The c.7G>C (p.V3L) alteration is located in exon 1 (coding exon 1) of the OSGIN2 gene. This alteration results from a G to C substitution at nucleotide position 7, causing the valine (V) at amino acid position 3 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
