Genetic basis of type 2 diabetes--recommendations based on meta-analysis

Objective:
Despite intensive effort to understand the genetic basis of type 2 diabetes, only a few genes responsible for relatively rare monogenic and syndromic subsets of diabetes are known; however, gene(s) responsible for genetic predispositions to common type 2 diabetes are unknown. The current study was obtained a better understanding of the genetic architecture of type 2 diabetes.
Materials And Methods:
Comprehensive literature search was performed and the extracted data was analyzed. The proportion of variance explained by validated genetic factors for a range of metabolic quantitative traits was analyzed.
Results:
A fully elucidated landscape of type 2 diabetes genetics may well depict perhaps a hundred or more common variants individually with low impact on disease.
Conclusions:
Every individual harbors a combination of different risk alleles and only special compilations of these variants in combination with other genetic and non-genetic components will likely lead to disease.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
