Key result
Polygenic forms underlie ~80% of severe hypertriglyceridemia cases and link to MASLD, while FCS links to pancreatitis.
Why the study?
Severe hypertriglyceridemia carries risks of acute pancreatitis, metabolic dysfunction, and cardiovascular events, with a genetic architecture ranging from rare monogenic variants causing FCS to more prevalent polygenic syndromes.
What are the genetic architectures, clinical correlates, and treatment responses in adults with severe hypertriglyceridemia?
Systematic Review (n=2,521)
What are the genetic architectures, clinical correlates, and treatment responses in adults with severe hypertriglyceridemia?
Severe hypertriglyceridemia exhibits a genotype–phenotype gradient where rare monogenic forms are linked to recurrent pancreatitis and common polygenic forms are associated with metabolic dysfunction and MASLD, supporting precision-medicine approaches.

Most severe hypertriglyceridemia is polygenic, not FCS; confirms distinct pancreatitis versus MASLD risks guiding targeted evaluation.
Luca et al. (2025) conducted a systematic review in Severe hypertriglyceridemia (n=2,521). Genetic variants (biallelic vs polygenic) was evaluated on Genotype, polygenic risk score, TG levels, metabolic comorbidities, hepatic steatosis, pancreatitis, and treatment response. Familial chylomicronemia syndrome accounted for <5% of severe hypertriglyceridemia cases with >70% pancreatitis prevalence, whereas polygenic forms represented 70-80% of cases with >70% MASLD.
