The c.1068G>C (p.Q356H) alteration is located in exon 8 (coding exon 8) of the RPAP2 gene. This alteration results from a G to C substitution at nucleotide position 1068, causing the glutamine (Q) at amino acid position 356 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
