In order to determine the prevalence of Korean PKD2 patients, all the coding sequences of PKD2 were screened using TDGS and direct sequencing in 46 randomly selected ADPKD patients (group 1).
Mutation or deletion of the gene encoding for PC2 results in autosomal dominant polycystic kidney disease (ADPKD), a condition characterized by numerous fluid-filled cysts.
These data reveal a pathway connecting TNF-alpha signaling, polycystins and cystogenesis, the activation of which may reduce functional polycystin-2 below a critical threshold, precipitating the ADPKD cellular phenotype.
Autosomal dominant polycystic kidney disease (ADPKD) is characterized by a variable renal disease progression, which is primarily due to genetic heterogeneity (PKD1 vs. PKD2).
Autosomal dominant polycystic kidney disease (PKD) is an inherited disease that results from mutations in either polycystin (PKD1) or polycystin 2 (PKD2), both of which are large, complex, and multifunctional proteins whose loss results in the development of numerous fluid-filled cysts and fibrosis that compromise renal function.
Technical Evaluation: Identification of Pathogenic Mutations in PKD1 and PKD2 in Patients with Autosomal Dominant Polycystic Kidney Disease by Next-Generation Sequencing and Use of a Comprehensive New Classification System.
Autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD) are genetically distinct, with ADPKD usually caused by the genes <i>PKD1</i> or <i>PKD2</i> (encoding polycystin-1 and polycystin-2, respectively) and ARPKD caused by <i>PKHD1</i> (encoding fibrocystin/polyductin [FPC]).
The Polycystic Kidney Disease 2 (Pkd2) gene is mutated in autosomal dominant polycystic kidney disease (ADPKD), one of the most common human monogenic disorders.
Autosomal Dominant Polycystic Kidney Disease (ADPKD) typically results from a mutation in the PKD1 and PKD2 genes, which code for polycystin-1 (PC1) and polycystin-2 (PC2), respectively.
Despite more than a decade of work on the principal ADPKD genes, PKD1 and PKD2, questions remain about the basis of cystic disease and the role of extracellular matrix in ADPKD pathology.
Herein, we describe and characterize a novel missense mutation in the PKD2 gene (c.1320G>T) in a 41-year-old White man with kidney cysts and a family history of ADPKD.
