E78.01
Familial hypercholesterolemia
Clinical Classification Guidelines
Medical Intelligence & Overview
Familial hypercholesterolemia is a genetic condition characterized by high levels of low-density lipoprotein (LDL) cholesterol, often called 'bad cholesterol.' This condition can lead to the early development of heart disease if not managed properly. It is inherited in an autosomal dominant manner, meaning only one copy of the altered gene can cause the disorder. Recognizing and understanding familial hypercholesterolemia is important for timely intervention and reducing health risks.
Causes & Symptoms
Clinical Causes: Genetic mutation affecting LDL receptor function Inheritance of defective genes from one or both parents Family history of high cholesterol or early heart disease
Key Symptoms: High levels of LDL cholesterol detected through blood tests Xanthomas — fatty deposits under the skin, often on the elbows or knees Corneal arcus — a gray or white ring around the cornea of the eye Early onset of cardiovascular disease, including heart attacks, often before age 55 in men and 65 in women
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves blood tests to measure cholesterol levels, along with a detailed family medical history. Genetic testing can identify specific mutations associated with familial hypercholesterolemia. Clinicians may also examine physical signs like xanthomas or corneal arcus, and assess the patient for early signs of cardiovascular issues.
Treatment Protocols: Treatment strategies focus on managing cholesterol levels and reducing cardiovascular risk. They include lifestyle modifications such as a healthy diet, regular exercise, and smoking cessation. Medications, particularly statins, are commonly prescribed to lower LDL cholesterol. In some cases, additional therapies like PCSK9 inhibitors or LDL apheresis may be recommended. Regular medical monitoring is essential to adjust treatment plans and prevent complications.
