The c.2286G>C (p.Q762H) alteration is located in exon 19 (coding exon 19) of the CEP89 gene. This alteration results from a G to C substitution at nucleotide position 2286, causing the glutamine (Q) at amino acid position 762 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
