Ambry Genetics

Jul 12, 2023

The c.3526C>G (p.Q1176E) alteration is located in exon 22 (coding exon 21) of the RPAP1 gene. This alteration results from a C to G substitution at nucleotide position 3526, causing the glutamine (Q) at amino acid position 1176 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
