| Abstract: | Background: Multiple familial hypercholesterolemia (FH) screening strategies are recommended, but how they work together within a population remains poorly understood. Here, we aimed to compare the characteristics of children diagnosed through a universal screening program with those of adults identified through opportunistic screening. Methods: In this retrospective cross-sectional study, we analyzed the clinical and genetic characteristics of children and adults with genetically confirmed heterozygous FH (HeFH). Results: Out of 442 children and 299 adults with a definite or probable FH based on clinical criteria, 39 (13.0%) adults and 197 (44.6%) children had also a genetic HeFH. FH causative variants were present in low-density lipoprotein receptor (LDLR) in 159 (67.4%) patients and in apolipoprotein B (APOB) in 77 (32.6%) patients. The combined screening approach identified 44 disease-causing variants, of which 2 and 25 were unique to the adult and pediatric cohort, respectively. The proportion of children with missense variants was significantly higher (172 [87.3%] vs. 27 [69.2%]; p = 0.005), whereas the proportion of termination variants was significantly lower (20 [10.2%] vs. 11 [28.2%]; p = 0.002) compared to the adult group. Adults had higher adjusted low-density lipoprotein cholesterol compared to children. Conclusions: Our study suggests that opportunistic adult screening identifies more severe FH phenotypes, while universal pediatric screening detects milder cases. |
