Imputation and subset-based association analysis across different cancer types identifies multiple independent risk loci in the TERT-CLPTM1L region on chromosome 5p15.33

Zhaoming Wang, +350 more
TL;DR: Allele-specific effects on DNA methylation were seen for a subset of risk loci, indicating that methylation and subsequent effects on gene expression may contribute to the biology of risk variants on 5p15.33, to an extent not previously observed in other cancer susceptibility loci.
Journal ArticleDOI

Polymorphisms in nucleotide excision repair genes, arsenic exposure, and non-melanoma skin cancer in New Hampshire.

TL;DR: Findings indicate a reduced NMSC risk in relation to XPD Asp312Asn and Lys751Gln variants, and support the hypothesis that NER polymorphisms may modify the association between N MSC and arsenic.
Journal ArticleDOI

Estimated exposure to arsenic in breastfed and formula-fed infants in a United States cohort.

TL;DR: The findings suggest that breastfed infants have lower arsenic exposure than formula-fed infants, and that both formula powder and drinking water can be sources of exposure for U.S. infants.
Journal ArticleDOI

Power and sample size calculations for generalized regression models with covariate measurement error

TL;DR: This paper derives a novel measurement error corrected power function for generalized linear models using a generalized score test based on quasi-likelihood methods and demonstrates the improved properties of the power calculations with simulations and numerical studies.
