The vacuolar protein sorting 35 (VPS35) gene located on chromosome 16 has recently emerged as a cause of late-onset familial Parkinson's disease (PD) (PARK17). The gene encodes a 796-residue protein nearly ubiquitously expressed in human tissues. The protein localizes on endosomes where it assembles …What does Vps35-PD stand for?
VPS35 -related Parkinson disease ( VPS35 -PD) is defined as Parkinson disease caused by heterozygous VPS35 pathogenic variants. Currently, the only known VPS35 variant with confirmed pathogenicity is c.1858G>A (p.Asp620Asn).Is aspartic-acid-to-asparagine mutation in Vps35 a genetic determinant of disease?
Exome analysis suggests that an aspartic-acid-to-asparagine mutation within vacuolar protein sorting 35 (VPS35 c.1858G>A; p.Asp620Asn) is the genetic determinant of disease.Do PD-associated Vps35 mutations cause mitochondrial fragmentation and cell death?
Here we demonstrate that PD-associated VPS35 mutations caused mitochondrial fragmentation and cell death in cultured neurons in vitro, in mouse substantia nigra neurons in vivo and in human fibroblasts from an individual with PD who has the VPS35 (D620N) mutation.
