Crohn-s-Disease-WES-meta

Sequencing of over 100,000 individuals identifies multiple genes and rare variants associated with Crohn’s disease susceptibility

Synopsis

IBD exome-wide assocaition statistics from the meta-analysis of two callsets: Nextera and Twist. We used the fixed-effect meta-analysis in METAL. Column headers are self-explanatory. Allele2 is the tested/effect allele.
