Hereditary Disorders of Cardiovascular Calcification

Area of Science:

• Genetics
• Cardiovascular Medicine
• Metabolic Disorders

Background:

• Arterial calcification is common in elderly, atherosclerosis, renal failure, and diabetes.
• Early-onset arterial calcification in young individuals indicates a potential hereditary disorder.
• Monogenic disorders are rare but significant causes of premature cardiovascular calcification.

Purpose of the Study:

• To provide an overview of monogenic disorders causing early-onset arterial calcification.
• To classify these disorders based on the function of the affected genes.
• To emphasize the importance of genetic work-up for early diagnosis and management.

Main Methods:

• Literature review and synthesis of existing data on monogenic arterial calcification disorders.
• Classification of disorders based on affected gene pathways: purine/phosphate metabolism, interferonopathies, and Gaucher disease.
• Clinical presentation and genetic basis of each disorder category were analyzed.

Main Results:

• Monogenic disorders causing early arterial calcification are rare and can be categorized into three main groups.
• Group 1: Disorders of altered purine and phosphate/pyrophosphate metabolism.
• Group 2: Interferonopathies. Group 3: Gaucher disease.

Conclusions:

• Early-onset arterial calcification necessitates investigation for underlying hereditary conditions.
• Identifying the specific genetic defect is crucial for accurate diagnosis and targeted therapy.
• Prompt genetic evaluation can lead to timely intervention and improved patient outcomes.
