Ambry Genetics

Oct 28, 2023

The c.220G>T (p.V74F) alteration is located in exon 1 (coding exon 1) of the CCNI2 gene. This alteration results from a G to T substitution at nucleotide position 220, causing the valine (V) at amino acid position 74 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
