Clinical trial NCT00187668: Study Of PHarmacogenetics in Ethnically Diverse Populations (SOPHIE Study)
Official title: Study Of PHarmacogenetics in Ethnically Diverse Populations (SOPHIE Study)
Study type: OBSERVATIONAL
Overall status: COMPLETED
Conditions: Focus Groups
Keywords: Healthy Cohort
Lead sponsor: University of California, San Francisco
Sponsor class: OTHER
First posted: 2005-09-16
Enrollment: 500
Sex: ALL
Minimum age (years): 18
Maximum age (years): 40
Standard ages: ADULT
Accepts healthy volunteers: yes
Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Healthy participants that are willing to be called back for subsequent genotype to phenotype studies.

Brief summary: Collect DNA from well-characterized healthy volunteers.

Detailed description: DNA and plasma will be used to identify and determine allele frequencies of genetic variants in membrane transporters and other genes relevant to human disease or drug response, including drug metabolizing enzymes, collagen, race/ethnicity, neurovascular disease, asthma/allergy/lung disease, and cardiovascular disease. This phase of the study will serve as the hypothesis-generating phase for future studies by identifying genetic variants and determining allele frequencies among an ethnically diverse cohort of healthy volunteers. Future investigations (separate IRB applications) will attempt to correlate genotypes to phenotypes among this cohort of volunteers. The allele identification and frequency data from this group of healthy volunteers will also be used to design association studies in relevant disease populations.

Determine if identified sequence variants are associated with gain or loss of in vitro biologic function using lymphocytes obtained from patients.
