Melatonin receptor type 1A gene linked to Alzheimer's disease in old age.

ABSTRACT: Disruption of the circadian rhythms is a frequent preclinical and clinical manifestation of Alzheimer's disease. Furthermore, it has been suggested that shift work is a risk factor for Alzheimer's disease. Previously, we have reported association of intolerance to shift work (job-related exhaustion in shift workers) with a variant rs12506228A, which is situated close to melatonin receptor type 1A gene (MTNR1A) and linked to MTNR1A brain expression levels. Here, we studied association of that variant with clinical and neuropathological Alzheimer's disease in a Finnish whole-population cohort Vantaa 85+ (n = 512, participants over 85 years) and two follow-up cohorts. Rs12506228A was associated with clinical Alzheimer's disease (p = 0.000073). Analysis of post-mortem brain tissues showed asso
