Corticosterone methyloxidase deficiency is a rare genetic disorder caused by a mutation in the CYP11B1 gene. This gene is responsible for producing an enzyme called corticosterone methyloxidase, which is involved in the production of cortisol, a hormone that helps regulate the body's response to stress. People with this disorder have a deficiency of this enzyme, which leads to an inability to produce cortisol. This can cause a variety of symptoms, including fatigue, weight gain, low blood pressure, and increased susceptibility to infections. Treatment typically involves hormone replacement therapy to help regulate cortisol levels.
