Monogenic ALB Variants as Determinants of Severe Hypercholesterolemia

J Am Coll CardiolPublished

  • Genetic association study in 2 population biobank cohorts
  • meta-analysis across cohorts (fixed-effects)

Authors' conclusion

ALB LoF variants represent a previously underrecognized monogenic cause of elevated LDL-C, with effect sizes slightly less than canonical familial hypercholesterolemia variants.

Study context

Population
Adult participants of Geisinger MyCode (Pennsylvania, US) and NIH All of Us biobanks with linked EHR and genetic data155,530 MyCode
Comparison
ALB loss-of-function (LoF) variant carriers vs noncarriers
  • ALB LoF variantsn = 77
Outcome
LDL-C levels (adjusted for lipid-lowering medication use)

Pooled result

As reported in the abstract

LDL-C and serum albumin
Increase in LDL-C, mg/dL (95% CI)
ALB LoF carriers vs Noncarriers
38.3(28.2–48.5)
Reduction in serum albumin, g/dL (95% CI)
ALB LoF carriers vs Noncarriers
0.69(0.60–0.78)
ALB LoF variant carrier frequency
1 of 7,289
Noncarriers: decrease in low-density lipoprotein cholesterol (LDL-C) (mg/dL) per 1 g/dL decrease in serum albumin
10.9 (95% CI: 10.4-11.4)

Further pooled results

LDL-C per decile of polygenic score for lower albumin (European ancestry)

Decrease in LDL-C (mg/dL) per decile
0.22 (95% CI: 0.17-0.26)
