Autosomal dominant polycystic kidney disease

Definition A late-onset, autosomal dominant disorder characterized by the progressive development of innumerable cysts in the kidney, leading to renal insufficiency. Associated with mutations in the PKD1 gene on chromosome 16 (16q13.3) in 85% of patients, or the PKD2 gene on chromosome 4 (4q21–23) in approximately 15% of cases PKD1 encodes the protein polycystin 1. PKD2 encodes the protein polycystin 2. Clinical features You’re Reading a…

Molecular genomics of bladder cancer

Overview Bladder cancers are heterogeneous at the molecular level with two distinct oncogenic pathways. Recent genomic and molecular studies have been focused on muscle invasive bladder cancer (MIBC). Molecular classification based on genetic and molecular alterations characterized by multiple platforms has been proposed for MIBC. Molecular classification is useful for prognostication and therapy response prediction. Dual-track pathway in bladder carcinogenesis Urothelial cancer (UC) develops via two…
