The c.764C>G (p.A255G) alteration is located in exon 10 (coding exon 10) of the PRPF40A gene. This alteration results from a C to G substitution at nucleotide position 764, causing the alanine (A) at amino acid position 255 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
