The c.997G>A (p.D333N) alteration is located in exon 11 (coding exon 11) of the RRP1B gene. This alteration results from a G to A substitution at nucleotide position 997, causing the aspartic acid (D) at amino acid position 333 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
