To Correct or not to Correct (for treatment): Estimating Pre-treatment LDL-C Co...
Stevens, C.A.T.; Elshorbagy, A.; Vallejo-Vaz, A.J.; Dharmayat, K.; Lyons, A.; Bourbon, M.; Chora, J.; Humphries, S.E.; Catapano, A.L.; Hovingh, G.Background and Aims: Pretreatment LDL-C measurements aid familial hypercholesterolaemia (FH) diagnosis, and are crucial in epidemiologic studies investigating FH, but are often unavailable because individuals are already on lipid-lowering medication (LLM). Several formulae have been reported to estimate pre-treatment LDL-C in people on LLM by ‘correcting’ their LDL-C concentrations for LLM type and dosage, base...
Case-level data sharing makes a difference in variant classification
Chora, J.R.; Tichý, L.; Lacocca, M.A.; Freiberger, T.; Bourbon, M.The American College of Medical Genetics and Genomics guidelines for variant classification are composed of several evidence criteria that, when combined, lead to a 5-tier pathogenicity variant classification. Several criteria rely on case-level data from patients, relatives, or controls with or without a particular variant of interest. (...)
Recommendations for LDLR variant interpretation by the ClinGen’s Familial Hyper...
Chora, J.R.; Iacocca, M.; Tichy, L.; Wand, H.; Kurtz, L.C.; Zimmermann, H.; Meredith, A.L.; Williams, M.; Humphries, S.E.; Hooper, A.J.; Brunham, L.Familial Hypercholesterolemia (FH): - Lipid metabolism autosomal dominant condition; - Elevated low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) values since childhood → increased risk of atherosclerotic cardiovascular disease; - High heterozygote prevalence (1/250-1/500); Homozygous rare (1/ 300 000- 1/ 1 000 000); - Caused by pathogenic variants in LDLR (>90%), APOB (5- 10%) and PCSK9 (1...

Pooling and expanding registries of familial hypercholesterolaemia to assess ga...
EAS Familial Hypercholesterolaemia Studies Collaboration; Vallejo-Vaz, A.J.; Akram, A.; Kondapally Seshasai, S.R.; Cole, D.; Watts, G.F.; Hovingh, G.K.BACKGROUND: The potential for global collaborations to better inform public health policy regarding major non-communicable diseases has been successfully demonstrated by several large-scale international consortia. However, the true public health impact of familial hypercholesterolaemia (FH), a common genetic disorder associated with premature cardiovascular disease, is yet to be reliably ascertained using simi...
Familial hypercholesterolaemia: a global call to arms
Vallejo-Vaz, A.J.; Kondapally Seshasai, S.R.; Cole, D.; Hovingh, G.K.; Kastelein, J.J.; Mata, P.; Raal, F.J.; Santos, R.D.; Soran, H.; Watts, G.F.Familial Hypercholesterolaemia (FH) is the commonest autosomal co-dominantly inherited condition affecting man. It is caused by mutation in one of three genes, encoding the low-density lipoprotein (LDL) receptor, or the gene for apolipoprotein B (which is the major protein component of the LDL particle), or in the gene coding for PCSK9 (which is involved in the degradation of the LDLreceptor during its cellular...
