Here, we report a follow-up study of a unique multigeneration family with bilineal ADPKD (NFL10) in which a PKD1 disease haplotype and a PKD2 (L736X) mutation co-segregated with 18 and 14 affected individuals, respectively.
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.
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.
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.
TRPC6 dysfunction has been associated with the onset of focal segmental glomerosclerosis; TRPP2 dysfunction is linked to autosomal-dominant polycystic kidney disease, TRPM6 mutations underlie hypomagnesemia with secondary hypocalcemia, and TRPV1 dysfunction is implicated in renal hypertension.
Here we show that the ADPKD missense variant TRPP2(D511V) greatly reduces TRPP2 protein stability, and that TRPP2(D511V) function can be rescued in vivo by small molecules targeting the TRPP2 degradation pathway.
Patients with ADPKD and a pancreatic cyst were 5.9 times more likely to have a PKD2 mutation than a PKD1 mutation after adjusting for age, race, sex, estimated glomerular filtration rate, liver volume, and total kidney volume.
PKD1 and PKD2 variants were identified by direct gene sequencing and/or multiplex ligation-dependent probe amplification (MLPA) in 125 unrelated patients of ADPKD.
