This study evaluated variants in seven amyloid-beta degrading genes (ACE, ECE1, ECE2, IDE, MME, PLAU, TF) for association with Alzheimer's disease (AD) risk and cognitive phenotypes in older adults. In the GERAD1 cohort (3,333 AD cases, 1,225 controls), a four-SNP ECE1 intragenic haplotype (rs212524/rs212525/rs2282714/rs212531) was significantly associated with increased AD risk (OR=1.61, P=0.00035) in APOE ε4 carriers. In the Lothian Birth Cohort 1936 (LBC1936), a two-SNP ECE1 haplotype (rs2282715/rs3026883) was associated with lower non-verbal reasoning scores (β=-0.19, P=0.00036) in APOE ε4 non-carriers. Meta-analysis of four cognitive cohorts confirmed ECE1 promoter region SNPs associated with non-verbal reasoning in APOE ε4 non-carriers. Functional analysis showed the ECE1 rs213045 (338C>A) variant affected promoter activity in neuroblastoma cell lines, suggesting tissue-specific regulation.
About ECE1
The protein encoded by this gene is involved in proteolytic processing of endothelin precursors to biologically active peptides. Mutations in this gene are associated with Hirschsprung disease, cardiac defects and autonomic dysfunction. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Sep 2009]
