Our gene expression co-variation network (Fig. 5) indicates that this gene co-varies with the Chr 1 positional candidate Dcaf8, as well as the Chr 2 candidates Arl6ip6 and Galnt13.The function of Galnt13 in the brain is not known, nor is function of Arl6ip6, but a recent GWAS of susceptibility to ischemic strokes identified SNPs of this gene (along with Fmnl2) as potential contributors to this phenotype [90]. This evidence concerns the gene ARL6IP6 and ischemic stroke.
