The c.1435G>A (p.V479M) 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 1435, causing the valine (V) at amino acid position 479 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
