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

Nov 18, 2022

The c.841G>C (p.A281P) alteration is located in exon 3 (coding exon 3) of the CDKN2AIP gene. This alteration results from a G to C substitution at nucleotide position 841, causing the alanine (A) at amino acid position 281 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
