Genetic Analysis of Thyrotoxic Periodic Paralysis
Thyrotoxic periodic paralysis (TPP) is characterized by episodes of reversible hypokalemia and weakness in thyrotoxic patients. It is commonly found in males of Asian descent and is also seen in individuals having Native American or Hispanic ancestry. Therefore genetic etiology has been hypothesized. This study, we aim to find the susceptibility genes that associate with TPP. Both candidate genes approach and genome wide association study have been conducted.

|Official Title:||Genetic Analysis of Thai Patients With Thyrotoxic Periodic Paralysis|
|Study Start Date:||January 2004|
|Estimated Study Completion Date:||December 2005|
This study is a genetic association study. It included 50 cases of TPP patients and 80 cases of male, hyperthyroid patients who didn't have hypokalemia as a well characterized controls. After informed consent were obtained, genomic DNA from leukocyte were extracted. Pooled DNA were constructed and whole genome scan using 10K GeneChip microarray were genotyped on pooled genomic DNA.
