Historical Perspective
Classification
Pathophysiology
Lipoid congenital adrenal hyperplasia is an autosomal recessive disease; characterized by deficiency of all adrenal hormones and increased corticotropin (ACTH) secretion.
- This disease is caused by gene mutations on chromosome 8. This gene mutation codes for a protein called steroid acute regulatory protein (StAR). StAR helps cholesterol transport from the outer to the inner mitochondrial membrane.
On microscopic histopathological analysis, progressive accumulation of cholesterol esters are characteristic findings of Lipoid congenital adrenal hyperplasia.
