The c.1489G>A (p.G497R) alteration is located in exon 15 (coding exon 13) of the CEP70 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. -
