The c.100C>G (p.L34V) alteration is located in exon 2 (coding exon 2) of the VSIG8 gene. This alteration results from a C to G substitution at nucleotide position 100, causing the leucine (L) at amino acid position 34 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
