The c.1489G>A (p.G497R) alteration is located in exon 10 (coding exon 9) of the RBBP8NL gene. This alteration results from a G to A substitution at nucleotide position 1489, causing the glycine (G) at amino acid position 497 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
