The c.2611C>G (p.L871V) alteration is located in exon 22 (coding exon 22) of the OVCH1 gene. This alteration results from a C to G substitution at nucleotide position 2611, causing the leucine (L) at amino acid position 871 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
