Ambry Genetics

Feb 05, 2024

The c.436A>G (p.I146V) alteration is located in exon 6 (coding exon 4) of the CPSF2 gene. This alteration results from a A to G substitution at nucleotide position 436, causing the isoleucine (I) at amino acid position 146 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
