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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.487G>A (p.A163T) alteration is located in exon 3 (coding exon 3) of the CDKN2AIP gene. This alteration results from a G to A substitution at nucleotide position 487, causing the alanine (A) at amino acid position 163 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
