Corticosterone methyloxidase type I (CMO-I) deficiency, also known as 18-hydroxylase deficiency or aldosterone deficiency among other names, is a genetic disorder that is autosomally linked and caused by a defective CYP11B2 gene. This gene encodes the cytochrome P450 11B2 mitochondrial protein, also called aldosterone synthase, which is used to catalyze the conversion of 18-hydroxycorticosterone to aldosterone. This leads to a decrease in the amount of aldosterone present in the cells, which is responsible for an increased amount of salt excreted in the urine, known as salt wasting. In CMO-I deficiency, aldosterone levels are so low that they are undetectable in plasma.
