The other T2DM and MS susceptibility genes including ATHS (atherosclerosis susceptibility, lipoprotein associated) (on chromosome 19p13.3-p13.2), AKT2 (murine thymoma viral homolog-2) (on chromosome 19q13.2), FFAR 1 (free fatty acids receptor 1) (on chromosome 19q13.12), FFAR 2 (on chromosome 19q13.12) and FFAR 3 (on chromosome 19q13.12) may also in linkage disequilibrium with the RETN gene (based on Ensembl database). Here, FFAR1 is linked to type 2 diabetes mellitus.
