Summary
This 2020 review in Nature Reviews Endocrinology examines genetic evidence to understand how pancreatic islet cell dysfunction arises in type 2 diabetes mellitus. The authors synthesise findings from genome-wide association studies and functional genetics to clarify the molecular and cellular basis of impaired insulin secretion and β-cell failure. The work is intended to bridge genetics and endocrine physiology to inform therapeutic targets.
Regional applicability
As a mechanistic review of diabetes genetics, the findings are globally applicable, including to United Kingdom clinical and research contexts. The genetic pathways identified are population-independent, though allele frequencies may vary across ancestry groups; UK diabetes care and research would benefit from this framework.
Key measures
Genetic variants associated with islet cell function; mechanisms of β-cell dysfunction; glucose regulation pathways
Outcomes reported
The paper synthesises genetic evidence to elucidate mechanisms of pancreatic islet cell dysfunction in type 2 diabetes mellitus. It reviews how genomic studies inform understanding of β-cell failure and glucose homeostasis.
