The c.1427A>G (p.H476R) alteration is located in exon 10 (coding exon 9) of the PRPF39 gene. This alteration results from a A to G substitution at nucleotide position 1427, causing the histidine (H) at amino acid position 476 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
