Aims:
Type 1 and type 2 diabetes, complicated with renal disease, have a significantly higher incidence in the Canary Islands than in mainland Spain and other European countries. Present-day Canarian inhabitants consist of a mixed population with North African indigenous and European colonizer ancestors who have rapidly evolved from a rural to an urban life style. The aim of this work was to assess the possible role of genetic and environmental factors on diabetes-related end-stage renal disease incidence in the Canary Islands.
Results:
For both types of diabetes there is an ethnic susceptibility increased by diabetes family history. Whereas the Y-chromosome does not play a significant role, mitochondrial DNA (mtDNA) haplogroup differences point to a maternal origin for this ethnic predisposition, confirming susceptible and protective effects for haplogroups J and T, respectively. In addition, urban life style seems to be an additional risk factor for type 1 diabetes.
Conclusions:
The maternal ethnic predisposition to diabetes complicated with kidney disease detected in the Canary Islands signals mtDNA and X-chromosome markers as the best candidates to uncover the genetic predisposition to this disease.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
