What is the Origin of TCF7L2 Gene?

The name is an acronym for Transcription Factor 7-Like 2, reflecting its biochemical role as a protein that binds to DNA to regulate the transcription of other genes. Its discovery and association with T2DM were major milestones in the field of human genetics and metabolic disease.

What is the Mechanism of TCF7L2 Gene?

The TCF7L2 protein acts as a nuclear effector of the canonical Wnt signaling cascade. It typically functions to regulate the expression of genes involved in glucose metabolism, particularly those controlling the proliferation and function of pancreatic beta cells and the incretin effect. Risk variants of the gene are thought to impair the ability of beta cells to secrete insulin in response to glucose, contributing directly to the pathophysiology of T2DM.

TCF7L2 Gene

Meaning

The TCF7L2 gene, or Transcription Factor 7-Like 2, is a gene that encodes a transcription factor critical to the Wnt signaling pathway, which is fundamentally involved in cell fate, proliferation, and metabolism. Clinically, specific polymorphisms within the TCF7L2 gene are recognized as the strongest and most consistently replicated genetic risk factors for Type 2 Diabetes Mellitus (T2DM). Variations in this gene significantly influence glucose homeostasis and insulin secretion.
