RTEL1 and Alzheimer disease: We observed increased expression of all three genes (RTEl1, RTEL1-TNFRSF6B, TNFRSF6B) associated with rs6062490, when comparing the single pair of homozygous-risk AD to homozygous non-risk control, but we observed inconsistent trends from the two donor pairs in which the AD patients were homozygous risk and controls were heterozygous non-risk.
