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 GeneticsJul 22, 2024The c.830C>T (p.S277F) alteration is located in exon 3 (coding exon 3) of the CDKN2AIP gene. This alteration results from a C to T substitution at nucleotide position 830, causing the serine (S) at amino acid position 277 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
