Popis: The uneven distribution of Alu repetitive elements in the human genome is related to specific functional properties of genomic regions. We report the identification of a locus associated with human longevity in one of the chromosomal regions with the highest density of Alu elements, in 1p35. The locus, corresponding to a (TG)n microsatellite in the YTHDF2 gene, was identified by characterizing an ‘‘anonymous’’ marker detectable through interAlu fingerprinting, which previously evidenced an increased homozygosity in centenarians. After genotyping 412 participants of different ages, including 137 centenarians, we confirmed the increased homozygosity in centenarians at this locus, and observed a concomitantly increased frequency of the most frequent allele and the corresponding homozygous genotype. Remarkably, the same genotype was associated with increased YTHDF2 messenger RNA levels in immortalized lymphocytes. Finally, YTHDF2 messenger RNA resulted to be mainly expressed in testis and placenta. The data suggest a possible role of this locus in human longevity.
