PST Linkage Based Analysis in the Family of More Than Two Members With Type 1 Diabetes in Taiwan (PATT)

June 10, 2014 updated by: Chang Gung Memorial Hospital

Parent-sibling Tracing (PST) Linkage Based Analysis in the Family of More Than Two Members With Type 1 Diabetes in Taiwan for Novel HLA and Non-HLA Candidate Risk Alleles Detection

The purpose of this study is to explore the susceptible genes for Type 1 diabetes in Taiwan through the new genetic study methods.

Detailed Description

As an unclear autoimmune disorder, the pathogenesis of type 1 diabetes (T1D) remains elusive. Among all the methods for studying diseases pathophysiology, genetic approach has valuable capability as being both hypothesis-testing and hypothesis-generating. Although geo-epidemiological studies show relatively higher prevalence of T1D in Caucasians than in Asians, whether genetic factors identified in T1D of Caucasians are essential for T1D in Asians is not yet clarified. Although the human leukocyte antigen (HLA) genotype variants have been reported to be associated with T1D, the odds ratio (ORs) is relatively low in Taiwan as comparing with western countries, some families are indeed more than one child with T1D. However, the genetic linkage study in T1D is still limited in Taiwan that hampered the drug development or research in T1D. Therefore, we intend to explore the susceptible genes for T1D of Taiwan in this study, which will provide further researcher directions for this disease.
