Genetic Identification of Monogenic Disorders in Early-onset Stroke Using Targeted Next Generation Sequencing Panel

NCT ID: NCT04485598

Last Updated: 2020-07-24

Basic Information

• Recruitment Status: COMPLETED
• Total Enrollment: 502 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2015-08-21
• Study Completion Date: 2020-05-22

Brief Summary

The study was designed as a multicenter multiracial prospective observational study of acute ischemic stroke and TIA patients across china. The purpose of this study is to determine the monogenic disorders incidence of Chinese early-onset stroke patients. We plan to consecutively enroll more than 500 patients with early-onset stroke(in the 18- to 45-year age range) admitted in stroke units within 7 days after symptoms onset in participating centers. These early-onset stroke patients are referred for targeted sequencing using 'cerebrovascular disease panel'. By analyzing the sequencing results, we intend to identify monogenic causes causing early-onset stroke and develop clinical algorithms that might assist the clinician in deciding in which early-onset stroke patients testing for monogenic causes of stroke.

Detailed Description

The study was designed as a multicenter multiracial prospective observational study of acute ischemic stroke and TIA patients across china. The purpose of this study is to determine the monogenic disorders incidence of Chinese early-onset stroke patients. We plan to consecutively enroll more than 500 patients with early-onset stroke(in the 18- to 45-year age range) admitted in stroke units within 7 days after symptoms onset in participating centers. Patients fulfilling all of the inclusion criteria and none of the exclusion criteria will be referred for targeted sequencing using 'cerebrovascular disease panel'. When one or multiple pathogenic or possible pathogenic exonic mutations are found, a Sanger Sequencing (SS) on somatic DNA from peripheral blood leukocyte of the index case and affected relatives will be performed for the screening of the same mutations. And the sporadic patient's mutations will be checked by SS in the unaffected family members. By analyzing the sequencing results, we intend to identify monogenic causes causing early-onset stroke and develop clinical algorithms that might assist the clinician in deciding in which early-onset stroke patients testing for monogenic causes of stroke.
