The c.232C>G (p.L78V) alteration is located in exon 2 (coding exon 1) of the SNN gene. This alteration results from a C to G substitution at nucleotide position 232, causing the leucine (L) at amino acid position 78 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
