Genes affected

CDKN2AIP (HGNC:24325): (CDKN2A interacting protein) The protein encoded by this gene regulates the DNA damage response through several different signaling pathways. One such pathway is the p53-HDM2-p21(WAF1) pathway, which is critical to the DNA damage response. Two transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Dec 20, 2023

The c.140C>T (p.A47V) alteration is located in exon 1 (coding exon 1) of the CDKN2AIP gene. This alteration results from a C to T substitution at nucleotide position 140, causing the alanine (A) at amino acid position 47 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
