The c.2437C>A (p.H813N) alteration is located in exon 23 (coding exon 23) of the PRPF40A gene. This alteration results from a C to A substitution at nucleotide position 2437, causing the histidine (H) at amino acid position 813 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
