Based on the study results a suggestive mechanism elucidating the association between FADS 2 gene polymorphism and lipid levels and type-2 diabetes susceptibility is as follows: FADS 2 gene encodes for the enzyme delta-6 desaturase which is a rate-limiting enzyme in polyunsaturated fatty acids (PUFA) metabolism. The gene discussed is FADS2; the disease is type 2 diabetes mellitus.
