▶Cerebrospinal fluid Aβ42 levels and APP processing pathway genes in Parkinson's diseaseAssociationN=246Lynn M. Bekris et al.(2015)· Movement Disorders
This case-control study examined genetic variation in APP processing pathway genes and their association with cerebrospinal fluid amyloid-beta 42 levels in Parkinson's disease patients (n=85) versus healthy controls (n=161). Two SNPs showed significant correlation with CSF Aβ42 in PD: APP rs466448 (lower levels, p=0.014) and APH1B rs2068143 (higher levels, p=0.002), while three SNPs correlated in controls: APP rs214484 and rs2040273, and PSEN1 rs362344 (all lower levels). Results suggest APP and APH1B genetic variants may modulate CSF Aβ42 levels in PD patients.
About APP
This gene encodes a cell surface receptor and transmembrane precursor protein that is cleaved by secretases to form a number of peptides. Some of these peptides are secreted and can bind to the acetyltransferase complex APBB1/TIP60 to promote transcriptional activation, while others form the protein basis of the amyloid plaques found in the brains of patients with Alzheimer disease. In addition, two of the peptides are antimicrobial peptides, having been shown to have bacteriocidal and antifungal activities. Mutations in this gene have been implicated in autosomal dominant Alzheimer disease and cerebroarterial amyloidosis (cerebral amyloid angiopathy). Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Aug 2014]
