Alpha B-Crystallin (CRYAB) is purported to be a metastasis suppressor protein, and lack or lower CRYAB expression is a prognostic biomarker for several types of cancer, such as that of the prostate and head and neck. Mutations in alpha-B crystallin gene (CRYAB) have been described to cause congenital cataracts, dilated cardiomyopathy and myofibrillar myopathy. Mutations in the alphaB-crystallin (CRYAB) gene, encoding a small heat shock protein with chaperone function, are a rare cause of myofibrillar myopathy with autosomal-dominant inheritance, late-onset and moderate severity. Mutations in the CRYAB gene, encoding alpha-B crystallin, cause distinct clinical phenotypes including isolated posterior polar cataract, myofibrillar myopathy, cardiomyopathy, or a multisystemic disorder combining all these features. CRYAB may be identified as a novel prognostic marker and targeting CRYAB may provide a promising strategy for NSCLC treatment.
