Insights
Homozygous familial hypercholesterolaemia, a rare genetic disorder, affects one in a million people. This report details three cases, including a fatal myocardial infarction in a young male and xanthomata in a 12-year-old girl.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Metabolic Disorders
Background:
- Familial hypercholesterolaemia (FH) is an autosomal dominant genetic disorder.
- Homozygous familial hypercholesterolaemia (HoFH) is a severe, rare form of FH, affecting approximately 1 in a million individuals.
- HoFH is characterized by extremely elevated low-density lipoprotein cholesterol (LDL-C) levels from birth, leading to premature cardiovascular disease.
Observation:
- This report presents three cases of HoFH from two distinct families.
- A 25-year-old male experienced extensive myocardial infarction, resulting in a fatal outcome.
- A 14-year-old male and a 12-year-old female presented with characteristic features, including multiple planar xanthomata and tuberose xanthomata.
Findings:
- The presented cases highlight the severe clinical manifestations of HoFH, including premature cardiovascular events.
- Xanthomata, indicative of severe hyperlipidemia, were observed in pediatric and adolescent patients.
- The fatal outcome in the young adult underscores the aggressive nature of untreated or inadequately treated HoFH.
Implications:
- Early diagnosis and aggressive management of HoFH are crucial to prevent premature cardiovascular complications.
- Genetic counseling and cascade screening are essential for families with HoFH.
- Further research into novel therapeutic strategies for HoFH is warranted to improve patient outcomes.
Abstract:
Homozygous familial hypercholesterolaemia is a rare disorder encountered in one in a million in the general population. Case reports of three patients from two families are presented. A 25 year male presented with extensive myocardial infarction and had a fatal outcome. His younger brother (14 years), as also a 12 year girl from another family with multiple planar xanthomata and tuberose xanthomata, are presented.

Lethal Alleles
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...

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
