Abstract

Two recent studies have identified that a rare coding variant (p.R47H) in exon 2 of triggering receptor expressed on myeloid cells 2 (TREM2) gene is associated with Alzheimer's disease (AD) susceptibility in Caucasians. This association was not successfully replicated in Han Chinese, where this variant was rare or even absent. Previously, we resequenced TREM2 exon 2 to investigate whether additional rare variants conferred risk to AD in our cohort. Although several new variants had been identified, none of them was significantly associated with disease susceptibility. Here, to test whether TREM2 is truly a susceptibility gene of AD in Han Chinese, we extend our previous study by sequencing the other four exons of TREM2 in 988 AD patients and 1,354 healthy controls. We provided the first evidence that a rare coding variant (p.H157Y) in TREM2 exon 3 conferred a considerable risk of AD in our cohort (Pcorrected = 0.02, odds ratio = 11.01, 95% confidence interval: 1.38-88.05). This finding indicates that rare coding variants of TREM2 may play an important role in AD in Han Chinese.

  • TREM2 variants associate with an increased risk of AD.

    “Importantly, TREM2 variants associate with an increased risk of AD [15, 25, 38–40].”
  • Genetic studies in East Asian populations have been unable to replicate the significance of the TREM2 p.R47H variant because it is rarely found in this population.

    “However, genetic studies in East Asian populations have been unable to replicate the significance of the p.R47H variant in TREM2, because it is rarely found in this population.”

  • The significance of TREM2 p.H157Y has been confirmed in the Chinese population.

    “For example, TREM2 p.H157Y (rs2234255) has been detected not only in Caucasians [35] but also in Chinese [40] and Japanese [24], and the significance of this variant has been confirmed in the Chinese population (Table 4) [40].”

  • TREM2 p.H157Y (rs2234255) has been detected in Caucasians, Chinese, and Japanese.

    “For example, TREM2 p.H157Y (rs2234255) has been detected not only in Caucasians [35] but also in Chinese [40] and Japanese [24], and the significance of this variant has been confirmed in the Chinese population (Table 4) [40].”

  • To date, thousands of Chinese and Japanese have been screened for the TREM2 p.R47H variant, and only three Japanese carriers have been reported.

    “To date, thousands of Chinese and Japanese have been screened for p.R47H variant, and only three Japanese carriers of this variant have been reported (Table 4) [38–42].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
