tumoral     --over  
with CCND3 in agressive B cell lymphoma
tumoral     --low  
in the development and progression of oral squamous cell carcinoma and in thyroid, colon, breast, prostate and superficial bladder carcinoma
tumoral   deletion    
deleted in leukemia and other cancers with poor prognosis (pancreas adenocarcinoma, esophageal squamous cell carcinoma), degraded by proteasomes in gliomas
tumoral     --low  
(when inhibited by AKT1) in aggressive breast cancer
tumoral germinal mutation

  • to advanced prostate carcinoma
  • to to the development of multiple endocrine tumors
  • to pituitary hyperplasia and tumorigenesis
  • to breast cancer
  • to Systemic lupus erythematosus (SLE)
  • Variant & Polymorphism other
  • genotype VV strongly associated with advanced prostate carcinoma
  • frequencies of CT genotype and T allele of CDKN1B were found to be higher in breast cancer patients than in controls
  • multiple independent SNPs increasing the risk of SLE
  • Candidate gene
    Therapy target
    modulation of CDKN1B could bolster vaccine-induced T-cell memory and protective immunity
    cardiovascularaquiredheart failure
    manipulation of CDKN1B protein levels could yield therapeutic benefits in the treatment of heart failure
