Gene Analysis and Treatment Optimization in Chinese Homozygous Familial Hypercholesterolemia
The Study of Gene Analysis and Treatment Optimization in Chinese Homozygous Familial Hypercholesterolemia

详细说明
To better understand the genetics basis for LDL-C elevation and develop an optimized lipid-lowering strategy, we propose to do the following studies:
- To establish a China HoFH registry, and collect DNA and blood samples from all available family members of each proband (pedigrees);
- To detect gene mutations known to cause FH and identify family suitable for future whole genome sequencing aimed to identify novel genes controlling cholesterol levels.
3.To establish the relationship between types of gene mutations and lipid and atherosclerosis profile, as well as responses to lipid-lowering agents.

plasma LDL-C reduction percentage with lipid-lowering drugs from pre-treatment to the last time follow-up time point plasma LDL-C reduction percentage calculation: "plasma LDL-C at pre-treatment time point" minus "plasma LDL-C at the last time follow-up time point", and then compared with "plasma LDL-C at pre-treatment time point", namely "plasma LDL-C reduction percentage". |
