The c.1538A>G (p.D513G) alteration is located in exon 16 (coding exon 14) of the CEP70 gene. This alteration results from a A to G substitution at nucleotide position 1538, causing the aspartic acid (D) at amino acid position 513 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
