The c.901A>G (p.K301E) alteration is located in exon 6 (coding exon 5) of the PRPF39 gene. This alteration results from a A to G substitution at nucleotide position 901, causing the lysine (K) at amino acid position 301 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
