Genetics of Insulin and Incretins in Cystic Fibrosis
NCT01852448 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 550
Last updated 2025-07-25
Summary
Cystic fibrosis related diabetes (CFRD) is associated with worse CF-relevant outcomes.
The mechanisms underlying CFRD development are not fully understood, but recent evidence suggests Type 2 Diabetes Mellitus (T2DM) mechanisms may be involved and may involve incretins (gut secreted hormones that augment insulin secretion in response to a nutrient load).
This study will examine the prevalence of Genome wide association study (GWAS)-implicated T2DM alleles (including TCF7L2) across the spectrum of glucose abnormalities in CF and will use this information to compare incretin and insulin secretion in non-diabetic children and adults with high risk and low risk alleles.
Conditions
Interventions
- GENETIC
-
Blood or Saliva Sample Collection
A blood or saliva sample will be obtained for genotyping of TCF7L2 and approximately ten other genes implicated in type 2 diabetes.
