Added comment: PMID: 26427795 - a loss of function variant (c.359delG p.K120fsX20) was identified in 2 affected adult siblings and a 13 yo normotriglyceridemic daughter of one of the siblings.
PMID: 21666694 - Lipoprotein profiles of the families of 4 individuals with CREB3L3 nonsense mutations showed a significantly elevated mean plasma TG level in 11 mutation carriers compared with 5 non-carrier first-degree relatives (9.67 ± 4.70 vs. 1.66 ± 0.55 mM, P = 0.021, Wilcoxon test). 3 of those families have the same variant - Lys245GlufsTer130, which has 126 (281,946 alleles) hets in gnomAD v2.1.
PMID: 32580631 - case-control analysis of nonmonogenic severe hypertriglyceridemia cases (N=265) vs normolipidemic controls (N=477), identified 5 cases with LoF variants (3 of whom had the Lys245GlufsTer130 frameshift) and none in controls. OR 20.2 (95% CI 1.11–366.1) p = 0.002, adjusted p = 0.03.
The frequency of Lys245GlufsTer130 is higher than expected for a dominant disorder, but other loss of function variants have been identified. The gene may be associated with variable penetrance. There are multiple supporting null mouse models with hyperlipidaemia.
