The c.313A>G (p.M105V) alteration is located in exon 4 (coding exon 4) of the PRPF40A gene. This alteration results from a A to G substitution at nucleotide position 313, causing the methionine (M) at amino acid position 105 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
