However, the SNP rs3802842 associated with colorectal cancer (Fig. 3b)24, as well as the ABCA7 Alzheimer’s disease25 (Fig. 3f) and the TNFAIP3 rheumatoid arthritis26 (Fig. 3g) loci, all possess strong signals that are not attributed to known CNV, Indel or STR co-localisations. This evidence concerns the gene TNFAIP3 and colorectal cancer.
