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 …

CDKN2A/B homozygous deletion is associated with early recurrence in meningiomas Acta Neuropathol. 2020 Sep;140(3):409-413. doi: 10.1007/s00401-020-02188-w.

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. All B*B birds shared the same CDKN2A/B haplotype whereas the B*N birds showed a high degree of haplotype diversity, suggesting this region harboured Sex‐linked barring. To define the size of the IBD region among individuals carrying the B ‐allele, six B*B and 20 B*N birds were sequenced up‐ and downstream of the identified IBD region ( Figure 3 ). 2017-01-10 · In summary, the loss CDKN2A and/or CDKN2A/B in five of the seven AciCC tumors sequenced by Kato and coworkers (2015) strongly suggests overlapping pathways with MASC. Tel-TrkC activates the cyclins. Loss of p15Inkb and p16Inka would result in failure to inhibit cyclins 4/6 2015-04-01 · Thus, the CDKN2A/B locus may be involved in T2D development by modulating both the metabolic and inflammatory components of the disease process.

Because the HPD logic is not yet clear, more data is needed to better understand the link between this genomic signature and the development of HPD. 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 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. Inclusion of CDKN2A/B status may further improve the risk stratification of ALL patients. Key Messages Although numerous studies have explored the prognostic significance of cyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) deletions in acute lymphoblastic leukaemia (ALL) patients, the results remain conflicting. 1997-01-01 · CDKN2A, the gene encoding the cell-cycle inhibitor p16CDKN2A, was first identified in 1994.

2021-01-14 Five single-nucleotide polymorphisms of CDKN2A/B (rs1063192, rs3218009, rs3217986, rs3217992, and rs3731257) were genotyped and underwent bioinformatic analysis. DNA from osteosarcoma individuals was isolated from frozen peripheral blood and DNA from healthy controls was extracted from fresh prepared peripheral blood. Conclusions: Our data suggest a potential role of CDKN2A/B gene loss and alteration of MDM2 on the establishment of HPD in NSCLC patients treated with immunotherapy.

The CDKN2A/B genes in the 9p21 chromosomal region are frequently involved in human cancer, including pediatric acute lymphoblastic leukemia (ALL). These genes encode 3 proteins that belong to the RB1 and TP53 pathways and act as tumor suppressors by regulating the G1/S checkpoint of the cell cycle. …

CDKN2A/B deletions and correlation with clinical outcome. Finally, to determine whether deletions of CDKN2A/B genes could impair response to treatment in BCR-ABL1–positive ALL patients, clinical data were collected from 81 patients.

Conclusions: GAs in CDKN2A/B may have a predictive and possibly a prognostic impact. Antibody information for antibodies HPA047838, CAB000093, CAB000445 and CAB018232 used in analysis of ENSG00000147889 / CDKN2A (ARF, CDK4I, CDKN2, CMM2, INK4, INK4a 2017-01-10 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. 2017-05-08 A role for CDKN2A/B homozygous deletion in MVNT has not previously been described, but has been observed in anaplastic ganglioglioma and anaplastic pilocytic astrocytomas [1, 9].
