The c.1429C>G (p.L477V) alteration is located in exon 10 (coding exon 10) of the RABEP2 gene. This alteration results from a C to G substitution at nucleotide position 1429, causing the leucine (L) at amino acid position 477 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
