Genome Wide Association Study of Serum 25 Hydroxyvitamin D in US Women

2018

[…] ispanic whites and African-Americans due to concerns about population stratification and racial differences in linkage disequilibrium (Stram and Seshan, ). We used expectation-maximization software (“hapassoc” package in R; Burkett et al., , ) to estimate haplotype frequencies and the association between 25(OH)D and each copy of the index haplotype, relative to the most common haplotype in non-His […]

Logistic Bayesian LASSO for Genetic Association Analysis of Data from Complex Sampling Designs

2017
J Hum Genet
PMCID: 5572548
PMID: 28424482
DOI: 10.1038/jhg.2017.43

[…] gher proportion of current smokers amongst cases than in controls for both whites and blacks. More details about these data can be found in Hofmann et al. Haplotype frequencies as estimated using the hapassoc software based on maximum likelihood estimation are shown in . They vary substantially between the two races as well as between cases and controls. These estimates are used as starting values […]

Association of rare haplotypes on ULK4 and MAP4 genes with hypertension

2016
BMC Proc
PMCID: 5133474

[…] The three standard approaches considered here—haplo.score, haplo.glm, and hapassoc—are based on the generalized linear model (GLM). In haplo.score, a global test of association as well as individual haplotype-specific tests are carried out using a score function. It estimat […]

[…] Association of genotypes in the Scandinavian 115 HSE cases, EIMS 217 MS cases and 211 controls who were positive for HSV-1 IgG was tested using the assoc and hapassoc commands in PLINK v1.06 (http://pngu.mgh.harvard.edu/~purcell/plink/index.shtml). P-values have not been corrected for multiple comparisons. The same analysis was performed including all indi […]

[…] sociations with rare haplotypes in 2 hypertension-associated genes, ULK4 and MAP4. They analyzed sliding haplotype windows of 5 variants using 4 haplotype association methods: haplo.score, haplo.glm, hapassoc, and logistic Bayesian LASSO (LBL) and the three collapsing methods (SKAT, SKAT-O and SKAT-RC, see Tables  and ). LBL models the probability of haplotypes given disease status. Unobserved hap […]
