The c.842G>A (p.R281K) alteration is located in exon 9 (coding exon 9) of the RRP1B gene. This alteration results from a G to A substitution at nucleotide position 842, causing the arginine (R) at amino acid position 281 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
