The c.1469G>A (p.R490Q) alteration is located in exon 11 (coding exon 11) of the RABEP2 gene. This alteration results from a G to A substitution at nucleotide position 1469, causing the arginine (R) at amino acid position 490 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
