A case of premature and recurrent myocardial infarction associated with ABCA-1 gene mutation.

Coronary heart disease (CHD) is the most important cause of cardiovascular death and when premature, it affects the most productive population of the community. Premature CHD usually has a specific etiology, which on diagnosis, might help in the secondary prevention in that individual. We report a case of young adult with recurrent myocardial infarction, who on evaluation had mildly reduced HDL and Protein C levels with elevated serum homocysteine. Clinical exome identified a possibly pathogenic variant of ABCA1 gene, associated with Tangier disease.
