Jul 13, 2021

The c.3298G>A (p.D1100N) alteration is located in exon 22 (coding exon 21) of the RPAP1 gene. This alteration results from a G to A substitution at nucleotide position 3298, causing the aspartic acid (D) at amino acid position 1100 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
