The purpose of this research study is to screen healthy African American and Caucasian persons for specific differences in genes that control how fats are processed in the body. Persons with the needed genotypes will be added to a database of healthy persons who may be asked to join a larger study comparing differences in botanical oil supplements on lipid metabolism and inflammatory biomarkers and future studies. A key hypothesis for the larger study is that variations in genes involved in lipid metabolism play a role in determining levels of long chain polyunsaturated fatty acids (LC-PUFAs).


Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Screening of Healthy Adults for Genetic Variations That Control Fatty Acid Processing

Further study details as provided by Wake Forest Baptist Health:

Primary Outcome Measures:
  • Determine the genotype at the rs174537 single-nucleotide polymorphism (SNP) in the fatty acid desaturate (FADS) gene cluster [ Time Frame: up to 52 months ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
A small saliva sample for screening purposes will be collected. If documentation from a personal physician of blood glucose and lipid levels are unavailable, we will collect a small tube (10-12 ml) of blood to determine these measurements.

Estimated Enrollment: 800
Study Start Date: September 2011
Estimated Study Completion Date: July 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
