The c.1204C>A (p.Q402K) alteration is located in exon 8 (coding exon 8) of the RABEP2 gene. This alteration results from a C to A substitution at nucleotide position 1204, causing the glutamine (Q) at amino acid position 402 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
