PMID: 26064873
Int J Genomics. 2015;2015:501617. doi: 10.1155/2015/501617. Epub 2015 May 04.

Population substructure is a well-known confounder in population-based case-control genetic studies, but its impact in family-based studies is unclear. We performed population substructure analysis using extended families of admixed population to evaluate power and Type I error in an...

Application of the experimental design of genome-wide association studies (GWASs) is now 10 years old (young), and here we review the remarkable range of discoveries it has facilitated in population and complex-trait genetics, the biology of diseases, and translation...

Current rare-variant, gene-based tests of association often suffer from a lack of statistical power to detect genotype-phenotype associations as a result of a lack of prior knowledge of genetic disease models combined with limited observations of extremely rare causal...

On combining family- and population-based sequencing data.

BMC proceedings

Katsumata Y, Fardo DW.
PMID: 27980632
BMC Proc. 2016 Oct 18;10:175-179. doi: 10.1186/s12919-016-0026-9. eCollection 2016.

Several statistical group-based approaches have been proposed to detect effects of variation within a gene for each of the population- and family-based designs. However, unified tests to combine gene-phenotype associations obtained from these 2 study designs are not yet...

Genetics of Type 2 Diabetes: Opportunities for Precision Medicine: JACC Focus Seminar.

Journal of the American College of Cardiology

Kim DS, Gloyn AL, Knowles JW.
PMID: 34325839
J Am Coll Cardiol. 2021 Aug 03;78(5):496-512. doi: 10.1016/j.jacc.2021.03.346.

Type 2 diabetes (T2D) is highly prevalent and is a strong contributor for cardiovascular disease. However, there is significant heterogeneity in disease pathogenesis and the risk of complications. Enormous progress has been made in our ability to catalog genetic...

Robust Rare-Variant Association Tests For Quantitative Traits in General Pedigrees.

Statistics in biosciences

Jiang Y, Conneely KN, Epstein MP.
PMID: 30643591
Stat Biosci. 2018 Dec;10(3):491-505. doi: 10.1007/s12561-017-9197-9. Epub 2017 Jun 05.

Next generation sequencing technology has propelled the development of statistical methods to identify rare polygenetic variation associated with complex traits. The majority of these statistical methods are designed for case-control or population-based studies, with few methods that are applicable...
