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.

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.
