    Insights

    A 10-year-old boy with homozygous familial hypercholesterolaemia died of a heart attack. Early screening for high cholesterol in children can prevent atherosclerosis development.

    Area of Science:

    • Pediatric Cardiology
    • Genetics
    • Metabolic Disorders

    Background:

    • Familial hypercholesterolaemia (FH) is a genetic disorder causing severely high cholesterol levels.
    • Homozygous FH is a rare and severe form, often leading to premature cardiovascular disease.

    Observation:

    • A 10-year-old boy with homozygous FH died from myocardial infarction.
    • He had a history of removed tendon xanthomas, indicating long-standing hyperlipidaemia.
    • His family members exhibited elevated cholesterol levels, suggesting a hereditary pattern.

    Findings:

    • The case highlights the critical, often fatal, consequences of undiagnosed homozygous familial hypercholesterolaemia in childhood.
    • Autopsy confirmed myocardial infarction as the cause of death.
    • Genetic screening revealed familial hypercholesterolaemia in his parents and siblings.

    Implications:

    • Early identification of hypercholesterolaemia through screening at-risk children is crucial.
    • Timely intervention can mitigate the progression of atherosclerosis and prevent premature cardiovascular events.
    • This case underscores the importance of family-wide screening for genetic lipid disorders.

    Agouti: A Lethal Allele
    Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

    Lipid-Lowering Drugs: Statins and Miscellaneous Agents

    Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

    Lipids: Dietary Sources and Requirements

    Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

    Cholesterol: Significance and Regulation

    Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
    Considering cholesterol and...

    Huntington Disease l: Introduction

    Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
