SREBF1 Polymorphism and Egg Yolk on Cardiovascular Disease Risk in Healthy Young Adults: a Randomised, Two-period, Single Blinded, Crossover Trial

Not Applicable
Suspended
Conditions
Healthy
GEN1 Gene Mutation
Interventions
Dietary Supplement: Egg yolks
Dietary Supplement: Macronutrients equivalent control
Registration Number
NCT04975048
Lead Sponsor
Shandong University
Brief Summary

Our previous analysis showed that sterol regulatory element binding protein gene (SREBF1) rs2236513/rs2297508/rs4925119 polymorphism modulated the relation between dietary cholesterol and serum low density lipoprotein cholesterol /serum total cholesterol. This study aims to confirm and extend this finding by characterizing the effects of cholesterol from egg yolks on lipid profiles in healthy young adults with different SREBF1 genetic makeup. 32 SREBF1 C/G/G minor allele carriers at rs2236513/rs2297508/rs4925119 and 32 SREBF1 AA/CC/AA major homozygotes at rs2236513/rs2297508/rs4925119 were enrolled to test their response to egg yolks.
