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.

Jun 28, 2022

The c.566A>T (p.N189I) alteration is located in exon 3 (coding exon 3) of the CDKN2AIP gene. This alteration results from a A to T substitution at nucleotide position 566, causing the asparagine (N) at amino acid position 189 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
