The aim of this meta-analysis was to comprehensively assess the prognostic value of CDKN2A/B deletions in ALL patients. CDKN2A gene deletion is associated with acute lymphoblastic leukemia. CDKN2A/B SNPs (rs1063192, rs3218009, rs3217986, rs3217992, and rs3731257) were genotyped. SNP rs3217992 is predictive for susceptibility to, and poorer prognosis of, osteosarcoma. The GA and AA genotypes of rs3217992 are related to elevated risk of osteosarcoma. The CDKN2A/B genes in the 9p21 chromosomal region are frequently involved in human cancer, including pediatric acute lymphoblastic leukemia (ALL).

Germline mutations in RB1 and p53, two genes essential for OS development, can increase disease risk [2-4]. The only genome-wide association study (GWAS) of OS in humans found two significant associations, one genic (GRM4) and the other in a large gene desert, suggesting The CDKN2A/B risk variant, rs4977756, and the CDKN2B risk variant, rs1412829 were inversely associated (p = 0.049 and p = 0.002, respectively) with absence of a mutated IDH1, i.e., the majority of patients homozygous for the risk allele showed no or low expression of mutated IDH1.

613-618. Mutant CDKN2A lacked the ability to bind to wild-type cdk4 and did not reconstitute the transcriptional activator, resulting in little or no expression of the reporter gene (Panel B). Konckdown of CDKN2A promotes the low grade gliomas to high grade gliomas. Western blot analysis revealed a markedly decreased expression of CDKN2A after tranfecting a pool of four siRNA duplexes for CDKN2A in HS-683 and H4 cell lines(A).

While no targeted therapeutic has been engaged in clinical trials, the prognostic impact has been studied by a number of meta-analyses. In majority of cases CDKN2A is inactivated by homozygous deletions. 2020-09-02 · Our findings reveal that MTSCCs with aggressive clinical behavior have progressed through clonal evolution; CDKN2A/B deletion and additional complex genomic abnormalities may contribute to this The CDKN2A homozygous deletion is an important prognostic factor for survival outcomes of IDH-mutant glioma patients across multiple histologic WHO grades with specific molecular features likely dependent on IDH-mutant status. Greater understanding of how identifying this deletion can assist in the … p16 (also known as p16 INK4a, cyclin-dependent kinase inhibitor 2A, CDKN2A, multiple tumor suppressor 1 and numerous other synonyms), is a protein that slows cell division by slowing the progression of the cell cycle from the G1 phase to the S phase, thereby acting as a tumor suppressor. It is encoded by the CDKN2A gene. (B) Stratification on both WHO 2016 classification and CDKN2A status.

N/A Deletions of CDKN2A/B (66/83, 80%), MAPK pathway gene alterations (49/65, 75%, most frequently affecting NF1, followed by BRAF and FGFR1) and mutations of ATRX or loss of ATRX expression (33/74, 45%) were the most common molecular alterations. 2021-01-11 · Among 507 patients with diverse tumors harboring CDK4/6 amplifications, CCND1/2/3 amplifications, or CDKN2A/B alterations, 99% (n = 501) had at least 1 deleterious co-alteration (median, 4 co-alterations [excludes the cyclin alteration]; range, 0–24) in tissue NGS and the remaining 6 patients whose tumors did not have a co-alteration only had a CDKN2A/B alteration.

CDKN2A/B deletion was associated with worse OS (HR 1.57, 95% CI 1.003–2.46) and PFS (HR 1.57, 95% CI 1.04–2.36) on MVA, but TERT mutation and EGFR amplification were not. BACKGROUND Cyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) encodes several tumor suppressor proteins. Aberrant genetic alterations in CDKN2A/B were found in some malignancies, which were believed to be associated with tumor originating and progression. CDKN2A CDKN2A Loss is present in 8.05% of AACR GENIE cases, with conventional glioblastoma multiforme, lung adenocarcinoma, pancreatic adenocarcinoma, glioblastoma, and bladder urothelial carcinoma having the greatest prevalence [ 4 ].

CDKN2A gene mutations involved in cancer impair production of functional p16(INK4A) or, less commonly, p14(ARF), which can result in uncontrolled cell growth and tumor formation. Somatic CDKN2A gene mutations have been found in some people with brain tumors and in children with a blood cancer called acute lymphoblastic leukemia.
