Association between a multi-locus genetic risk score and inflammatory bowel disease.

ABSTRACT: To date, the utility of single genetic markers to improve disease risk assessment still explains only a small proportion of genetic variance for many complex diseases. This missing heritability may be explained by additional variants with weak effects. To discover and incorporate these additional genetic factors, statistical and computational methods must be evaluated and developed. We develop a multi-locus genetic risk score (GRS) based approach to analyze genes in NADPH oxidase complex which may result in susceptibility to development of inflammatory bowel disease (IBD). We find the complex is highly associated with IBD (P = 7.86 × 10(-14)) using the GRS-based association method. Similar results are also shown in permutation analysis (P = 6.65 × 10(-11)). Likelihood ratio test shows that
