Homocystinuria

What is homocystinuria?

Homocystinuria is an inherited autosomal recessive trait. Both parents must have a copy of the same defective gene in order to pass the trait along to their offspring. Homocystinuria is just one of many traits that are caused by autosomal recessive gene abnormalities. In this case, the amino acid methionine is not metabolized appropriately, causing a wide variety of symptoms and physical characteristics. People in Ireland, Norway, Germany, and Quatar are affected more frequently than the general global population.

What are the symptoms of homocystinuria?

Homocystinuria affects the connective tissue, the central nervous system, and the heart. Physical characteristics include long limbs, a tall thin build, intellectual disabilities, seizures, eye problems, and psychiatric disorders. It must be noted that these are not all the possible symptoms and in many cases, symptoms are vague, making the disorder difficult to diagnose.

What treatment options are available for homocystinuria?

While there is no cure for homocystinuria, approximately half of the patient population responds well to B6 treatments. Another treatment option is eating a diet that contains very little methionine. All treatments should be administered under the supervision of a healthcare professional. Fortunately, early treatment for infants can help delay the onset of intellectual disability; however, all patients with homocystinuria are prone to blood clots throughout their lives.
