There is one clinical trial.
This study evaluates how genetic variations in complement, a part of the immune system, affect cardiovascular risk in adolescents.
Genetic variants including A>G polymorphisms at rs11569562 and/or rs2250656,.
Two specific single nucleotide polymorphisms (SNPs) in the intron for C3, rs11569562 and rs2250656, both with A>G polymorphisms, are associated with increased serum C3 levels, and increases in a variety of cardiovascular risk factors.
