Homozygous Familial Hypercholesterolemia Epidemiology Summary

• According to DelveInsight’s analysis, the total prevalent cases of HoFH in 7MM were found to be approximately 1,840 in 2025 and are estimated to rise with a significant CAGR throughout the study period.
• The United States accounted for the maximum number of diagnosed prevalent cases of HoFH which was estimated to be around 900 in 2025 and are anticipated to increase by a significant CAGR.
• As per DelveInsight’s analysis, the US alone accounted for about 50% of the total diagnosed prevalent cases of HoFH in 2025 among the 7MM.
• Assessments as per DelveInsight’s analysts showed that Germany accounted for the highest total diagnosed prevalent cases of HoFH in 2024 among EU4 and the UK and these cases are further expected to decrease during the forecasted period (2022-2036).
• HoFH was historically estimated to affect about 1 in 1,000,000 individuals in the general population. However, more recent molecular and genetic epidemiology studies indicate that the condition may be more common than previously thought, with revised estimates ranging from approximately 1 in 160,000 to 1 in 300,000 based on secondary data analyses.

Homozygous Familial Hypercholesterolemia (HoFH) Understanding and Diagnosis Algorithm

Homozygous Familial Hypercholesterolemia Overview

HoFH is a rare, inherited genetic disorder characterized by extremely high levels of low-density lipoprotein cholesterol (LDL-C) from birth, leading to early-onset and aggressive atherosclerotic cardiovascular disease. It is caused by mutations in genes involved in LDL metabolism, most commonly the LDL receptor (LDLR), apolipoprotein B (APOB), or PCSK9, resulting in severely impaired clearance of LDL cholesterol from the bloodstream. Unlike heterozygous familial hypercholesterolemia, HoFH occurs when defective genes are inherited from both parents, making the condition significantly more severe. Clinically, patients often present with cutaneous or tendon xanthomas in childhood, corneal arcus, and premature cardiovascular complications, sometimes developing as early as adolescence. Despite its rarity, HoFH carries a significant burden due to high morbidity, early mortality, and the need for lifelong intensive treatment, emphasizing the importance of early identification and management.

Homozygous Familial Hypercholesterolemia Diagnosis

The diagnosis of HoFH involves a combination of clinical assessment, lipid profiling, and genetic testing. Patients typically exhibit markedly elevated LDL-C levels (often >500 mg/dL if untreated), which is a key diagnostic feature. A family history of hypercholesterolemia or premature cardiovascular disease further supports the diagnosis. Physical signs such as xanthomas can provide early clinical clues. Genetic testing is considered the gold standard for confirming mutations in LDLR, APOB, or PCSK9 genes and helps differentiate HoFH from other lipid disorders. Additionally, imaging techniques such as coronary artery calcium scoring or carotid ultrasound may be used to evaluate the extent of cardiovascular involvement. Early and accurate diagnosis is critical for initiating aggressive lipid-lowering therapy and reducing the risk of severe cardiovascular events.
