Abstract

Background and Aims

Polygenic hypercholesterolemia has been suggested to explain the significant proportion of patients with a diagnosis of familial hypercholesterolemia (FH) based on clinical and biochemical criteria, but without any disease-causing mutation.

Methods

We evaluated the distribution of a polygenic risk score proposed by Talmud et al. (Lancet, 2013), consisting of 12 LDL cholesterol (LDL-C) raising variants (LDLc-score), in a large Italian population of adult patients diagnosed with clinical FH

Results

Within the LIPIGEN study, 875 mutation-positive (FH/M+) patients (females 54.75%, mean age 42.47±15.00 years) and 644 mutation-negative (FH/M-) patients (females 54.21%, mean age 49.73±13.54 years) were evaluated. FH/M- patients had lower mean levels of pre-treatment LDL-C than FH/M+ group (217.14±55.49 vs 270.52±68.59 mg/dL, p<0.0001). The mean value (±SD) of the LDLc-score was 1.00 (±0.18) in FH/M- patients and 0.94 (±0.20) in FH/M+ group (p-value <0.0001). Higher mean LDLc-score levels were observed among FH/M- having pre-treatment LDL-C levels in the range 150-350 mg/dL (150-249 mg/dL: 1.01 vs 0.91, p-value <.0001; 250-349 mg/dL: 1.02 vs 0.95, p-value=0.0001). A positive correlation between LDLc-score and pre-treatment LDL-C levels was observed among FH patients independently of the presence of causative mutations.

Conclusions

From these data, we suggest that variants in multiple LDL-cholesterol-raising genes can play a role in determining LDL-C levels even in patients with monogenic familial hypercholesterolemia. More data is needed to investigate the association between the polygenic score and the risk of atherosclerotic disease to support its use in clinical practice.
