RESUMO
Objective To screen new mutations of ANGPTL8 gene in severe hypertriglyceridemia population.Meth-ods We designed a capture array encompassing all coding regions of the target genes for next -generation sequencing (NGS)in a cohort of 43 unrelated patients with severe hypertriglyceridemia.First, to exclude known TG related gene mutations,then the ANGPTL8 mutation was screened and the Sanger sequencing was performed.In combina-tion with functional prediction and conservatism analysis, the pathogenic mutation was finally screened.Results After bioinformatics analysis, a new ANGPTL8 mutation was identified in 43 patients with severe hypertriglyceri-demia.Conclusions Through ANGPTL8 mutation screening for severe hypertriglyceridemia in this study, a new rare mutation is found.
