Genetic Analysis of TREM2 Variants in Tunisian Patients with Alzheimer's Disease.

ABSTRACT:

Objective

Rare variants in the TREM2 gene have been reported to significantly increase the risk of Alzheimer's disease in Caucasian populations. Hitherto, this association was not studied in North African populations. In this work, we aimed to study the association between TREM2 exon 2 variants and the risk of late-onset Alzheimer's disease (LOAD) in a Tunisian population.

Subjects and methods

We sequenced exon 2 of TREM2 in a Tunisian cohort of 172 LOAD patients and 158 control subjects. We used the Fisher exact test to compare the distribution of allelic frequencies between the two groups.

Results

We identified 4 previously reported nonsynonymous variants (p.Asp39Glu, p.Arg62His, p.Thr96Lys, and p.Val126Gly) and 1 novel synonymous variant (p.Gln109Gln), none of whic
