Common variants of human TERT and TERC genes and susceptibility to sporadic Alzheimers disease
Studies investigating telomere length in association with cognitive decline, dementia, and sporadic Alzheimer's disease (AD) have frequently found shorter telomeres to be associated with the development of AD and telomerase expression with pathological processes in AD. Human telomerase is constituted by two components: the telomerase reverse transcriptase (TERT) and the telomerase RNA component (TERC). Genetic variation at the two loci has been investigated in relation to telomere length, longevity, and common diseases of advanced age, but not in relation to AD.
