Genome-wide association study identified ATP6V1H locus influencing cerebrospinal fluid BACE activity.


ABSTRACT: BACKGROUND:The activity of cerebrospinal fluid (CSF) ?-site APP cleaving enzyme (BACE) is a potential diagnostic biomarker for Alzheimer disease (AD). METHODS:A total of 340 non-Hispanic Caucasian participants from the Alzheimer's Disease Neuroimaging Initiative cohort (ADNI) database were included in this study with quality-controlled CSF BACE and genotype data. Association of CSF BACE with the genetic variants of single nucleotide polymorphisms (SNPs) was assessed using PLINK under the additive genetic model. The P values of all SNPs for CSF BACE were adjusted for multiple comparisons. RESULTS:One SNP (rs1481950) in the ATP6V1H gene reached genome-wide significance for associations with CSF BACE (P?=?4.88?×?10-?9). The minor allele (G) of rs1481950 was associated with higher CSF BACE activity. Although seven SNPs in SNX31, RORA, CDH23, RGS20, LRRC4C, MAPK6PS1 and LOC105378355 did not reach genome-wide significance (P?
