Ambry Genetics

Dec 21, 2022

The c.1346G>A (p.R449H) alteration is located in exon 11 (coding exon 9) of the CPSF2 gene. This alteration results from a G to A substitution at nucleotide position 1346, causing the arginine (R) at amino acid position 449 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
