Abstract
OBJECTIVE To identify rare coding variants segregating with late-onset Alzheimer disease (LOAD) in Caribbean Hispanic families. METHODS Whole-exome sequencing (WES) was completed in 110 individuals from 31 Caribbean Hispanic families without APOE ε4 homozygous carriers. Rare coding mutations segregating in families were subsequently genotyped in additional families and in an independent cohort of Caribbean Hispanic patients and controls. SRCAP messenger RNA (mRNA) expression was assessed in whole blood from mutation carriers with LOAD, noncarriers with LOAD, and healthy elderly controls, and also from autopsied brains in 2 clinical neuropathologic cohort studies of aging and dementia. RESULTS Ten ultra-rare missense mutations in the Snf2-related CREBBP, activator protein (SRCAP), were found in 12 unrelated families. Compared with the frequency in Caribbean Hispanic controls and the Latino population in the Exome Aggregation Consortium, the frequency of SRCAP mutations among Caribbean Hispanic patients with LOAD was significantly enriched (p = 1.19e-16). mRNA expression of SRCAP in whole blood was significantly lower in mutation carriers with LOAD, while the expression in whole blood and in the brain was significantly higher in nonmutation carriers with LOAD. Brain expression also correlated with clinical and neuropathologic endophenotypes. CONCLUSIONS WES in Caribbean Hispanic families with LOAD revealed ultra-rare missense mutations in SRCAP, a gene expressed in the brain and mutated in Floating-Harbor syndrome. SRCAP is a potent coactivator of the CREB-binding protein and a regulator of DNA damage response involving ATP-dependent chromatin remodeling. We hypothesize that increased expression in LOAD suggests a compensatory mechanism altered in mutation carriers.

[PMID: 28108637 PMCID: PMC5317377 DOI: 10.1212/wnl.0000000000003614] [Citation(s) in RCA: 45] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Accepted: 11/14/2016] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE To interrogate a poly-T variant (rs10524523, '523) in TOMM40, a gene adjacent to the APOE gene on chromosome 19, in older persons with APOE ε3/3 homozygosity for association with cognitive decline, the clinical hallmark of Alzheimer disease (AD). METHODS Data came from participants in 2 cohort studies of aging and dementia who underwent annual clinical evaluations for up to 21 years. APOE and TOMM40'523 genotypes were determined from DNA from blood or brain samples. Linear mixed models compared the rates of decline in cognition among APOE ε3/3 carriers with different '523 genotypes. RESULTS The 1,170 APOE ε3/3 homozygotes were of European ancestry, were free of dementia at baseline, and had an average age of 78.5 years at baseline. Three major genotypes at the '523 variant were linked to APOE ε3/3; 26.5% had 2 short poly-Ts (S/S), 48.5% had 1 short and 1 very long poly-T (S/VL), and 24.0% had 2 very long poly-Ts (VL/VL). Participants with '523-S/S had faster decline in global cognition than participants with '523-S/VL or VL/VL (p = 0.002). The same association was observed for episodic memory (p < 0.001) and semantic memory (p = 0.003) but not for working memory, perceptual speed, or visuospatial ability. CONCLUSIONS Our data reveal an association of APOE ε3/3-TOMM40'523 haplotypes with cognitive decline in community-based older persons such that the S/S poly-T genotype is related to faster cognitive decline, primarily in the domains of episodic and semantic memory.
