Hartnup Disease is a rare, inherited disorder that affects the body’s ability to absorb certain amino acids from food. It is caused by a genetic mutation in the SLC6A19 gene, which is responsible for producing proteins that are needed for absorbing certain amino acids. Symptoms of Hartnup Disease typically appear during childhood and can range from skin rashes and behavioral issues to neurological problems. Treatment of the disorder primarily involves using nutritional supplements to replace the amino acids that are not being absorbed correctly. Hartnup Disease is an inherited disorder caused by a deficiency in the absorption of certain amino acids from the gastrointestinal tract. It can lead to neurological symptoms such as ataxia, movement disorders, and seizures. Other symptoms may include poor growth, skin rashes, and pellagra-like dermatitis. Treatment involves dietary supplementation with essential amino acids as well as vitamin B6 and niacin.

What is Hartnup Disease?

Hartnup disease is an autosomal recessive metabolic disorder that affects the absorption of certain essential amino acids. It is caused by mutations in the SLC6A19 gene. The disease is named after Dr. John Hartnup, who first described the condition in 1956. Symptoms of Hartnup Disease include skin rashes, mental disturbances, poor muscle coordination, and pellagra-like symptoms.

Causes of Hartnup Disease

Hartnup disease is caused by mutations in the SLC6A19 gene which is responsible for regulating the absorption of tryptophan and other essential amino acids across the small intestine into the bloodstream. When this gene is mutated, it leads to a decrease in absorption resulting in deficiencies of these essential nutrients. This can lead to a variety of symptoms including skin rashes, mental disturbances, poor muscle coordination, and pellagra-like symptoms.

The most common cause of Hartnup disease is inheritance from one or both parents who carry a mutated copy of the SLC6A19 gene. In some cases, however, this mutation may occur spontaneously due to environmental factors such as exposure to certain chemicals or medications that can affect gene expression or cause changes in DNA structure.

Diagnosis and Treatment

Diagnosis of Hartnup disease typically involves testing for levels of tryptophan and its metabolites in urine samples as well as genetic testing for mutations in the SLC6A19 gene. Treatment typically includes supplementation with tryptophan and other essential amino acids as well as dietary modifications to increase absorption of these nutrients from foods such as fish and eggs.

What is Hartnup Disease?

Hartnup Disease is a rare genetic disorder that affects the body’s ability to absorb certain amino acids from food. It is caused by mutations in a gene that encodes for an enzyme called tryptophan-1-alpha hydroxylase. This enzyme helps to break down amino acids, which are essential building blocks for proteins. People with Hartnup Disease are unable to absorb some essential amino acids, leading to a deficiency of certain important proteins in the body.

Symptoms of Hartnup Disease

The most common symptoms of Hartnup Disease are neurological symptoms such as confusion and irritability, as well as skin problems such as pellagra and light sensitivity. Other symptoms can include poor growth, movement disorders, and difficulty digesting food. In more severe cases, people may experience seizures or mental retardation.

People with Hartnup Disease often have a characteristic rash on their face and limbs caused by pellagra, which is a condition where an inadequate intake of niacin (vitamin B3) leads to dermatitis and other skin problems. In addition, people with Hartnup Disease may be sensitive to sunlight due to their inability to metabolize tryptophan into vitamin D in the skin.

Other common symptoms of Hartnup Disease include poor growth due to nutritional deficiencies, movement disorders such as ataxia or spasticity, and difficulty digesting food due to malabsorption of amino acids from the diet. People with this condition may also have an increased risk of developing kidney stones due to inadequate levels of certain amino acids in the urine.

In some cases, people with Hartnup Disease may experience seizures or mental retardation due to brain damage caused by lack of essential nutrients in the diet. It is important for people with this condition to receive proper nutrition in order to prevent these complications from occurring.

Diagnosis of Hartnup Disease

Hartnup Disease is a rare, inherited disorder that affects how the body absorbs certain amino acids from food. Diagnosis of Hartnup Disease can be difficult and requires a combination of tests including physical exam, medical history, urine and blood tests, and genetic testing.

– A physical exam may be performed to check for physical symptoms associated with nutritional deficiencies.
– Medical history is also important in the diagnosis of Hartnup disease. The doctor may ask questions about family medical history as this condition is inherited.
– Urine and blood tests are done to check levels of amino acids in the body. These tests can reveal an increased excretion of certain amino acids in patients with Hartnup disease.
– Genetic testing is done to confirm a diagnosis of Hartnup disease by identifying mutations in the SLC6A19 gene which causes the disorder.

When diagnosing Hartnup disease it is important for health care professionals to consider other potential causes for any nutritional deficiencies or elevated levels of amino acids seen on lab tests. Treatment for this disorder focuses on controlling symptoms and preventing complications through dietary modifications and supplements as necessary
