The c.2308G>A (p.D770N) alteration is located in exon 19 (coding exon 19) of the CEP89 gene. This alteration results from a G to A substitution at nucleotide position 2308, causing the aspartic acid (D) at amino acid position 770 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
