Hyperlysinemia, Type 1 (AASS), is a metabolic genetic condition that is caused by excess lysine in the blood. Lysine is an essential amino acid (building blocks of proteins), which means the body does not make lysine naturally and it must be obtained through our diets. Hyperlysinemia, Type 1 (AASS), is caused by a deficiency of the enzyme that normally breaks down lysine in the body, which causes an excess amount of lysine in the blood. Earlier studies associated hyperlysinemia, type 1 (AASS) with severe intellectual disability, but this is no longer believed after further cases have been reported having normal intelligence. Most commonly, individuals with hyperlysinemia, Type 1 (AASS) do not have symptoms, and are usually unaware they have the condition.
Common symptoms that have been associated with increased lysine:
Seizures (non specific)
Low muscle tone (hypotonia)
Delayed psychomotor development
Intellectual disability (rarely)
Behavioral problems (rarely)
Treatment for Hyperlysinemia, Type 1 (AASS) includes a low lysine diet, in order to reduce the amount of lysine in the blood. This treatment has been found to help some affected individuals, but not all. For more information on Hyperlysinemia, Type 1 (AASS) visit Genetic Home Reference – Hyperlysinemia
There are several names that are used to describe Hyperlysinemia, Type 1 (AASS). Most often, medical professionals will simply call the condition Hyperlysinemia. Other names associated with Hyperlysinemia, Type 1 (AASS) include:

What health problems should I look for in Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a genetic condition that may cause a variable amount of neurological and behavioral symptoms. Although, about 50% of people who are found to have a genetic mutation associated with Hyperlysinemia, Type 1 (AASS) do not have symptoms and are usually unaware they have the condition. Regardless, if you suspect you may have Hyperlysinemia, Type 1 (AASS), you should watch out for certain symptoms. Individuals with Hyperlysinemia, Type 1 (AASS) usually begin displaying symptoms in infancy, and may include non-specific seizures, vomiting, troubles with eating, delayed motor skills, low muscle tone, delayed speech and reaching other milestones such as sitting up and standing.
With age, people with Hyperlysinemia, Type 1 (AASS) may still experience seizures and delayed speech and motor skills. Also, they may show decreased attention span and symptoms similar to ADHD. Some affected individuals may experience issues with the eyes, dislocation of the lens, anemia and sometimes non-specific gastrointestinal issues. Again, Hyperlysinemia, Type 1 (AASS) is described as a condition with extreme variability, meaning affected individuals will have varying symptoms at different times of their lives.

What gene change causes Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a genetic condition caused by changes or mutations in the AASS gene. This gene provides instructions to make the enzyme responsible for breaking down lysine in the body. The enzyme is called aminoadipic semialdehyde synthase. Changes in the AASS gene cause a deficiency in this enzyme, and result in increased amounts of lysine in the blood and cerebral spinal fluid.
One step of lysine breakdown first converts lysine to saccharopine, which is further broken down to alpha-aminoadipate semialdehyde. As a result, saccharophine may also build up in the blood and urine, and may be referred to as a clinical variant of hyperlysinemia, type 1 (AASS), called saccharopinuria.
What does it mean to have inherited a variant in the gene for Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a genetic condition that is caused by genetic mutations in the AASS gene. Although, not all genetic mutations in the AASS gene cause Hyperlysinemia, Type 1 (AASS). Genetic testing is used to reveal if there is a genetic change in a specific gene. In the case of Hyperlysinemia, Type 1 (AASS), sometimes there are genetic changes in the AASS gene that are not disease causing or changes that are classified as variants of uncertain significance (VUS). These are genetic changes that have not been documented in the population enough to yet know whether they are harmful or benign.

Is there more than one test for Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a metabolic genetic condition that is caused by excess lysine in the body. It is caused by a genetic difference in the AASS gene, which is responsible for making the enzyme that breaks down lysine in the body. To see if a person has Hyperlysinemia, Type 1 (AASS) there are two different types of testing that can be done, genetic testing to see if there is a genetic change in the AASS gene or biochemical testing to see if there is an increase of lysine in the blood. Usually, biochemical testing may be the first step in diagnosis, and if lysine is found to be high, confirmatory testing of the AASS gene may be used.
Both genetic testing and biochemical testing involve a blood draw. They usually can be ordered after evaluation by a primary care doctor, medical geneticist or genetic counselor. If there is a suspicion for the disease, a person’s blood will be drawn and sent for testing. For genetic testing, DNA will be extracted from the blood for analysis, and sometimes saliva samples or cheek swabs can be used to gather DNA, depending on the lab that is being used. For biochemical testing, a blood draw is used to determine if lysine levels are elevated similarly to levels found in Hyperlysinemia, Type 1 (AASS).

Is it risky for me to get pregnant if I have Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a genetic condition that may present with a variety of symptoms. In Hyperlysinemia, Type 1 (AASS), a person has to be a carrier of two non-functioning genes to have the condition, which is also described as autosomal recessive inheritance. This means that both parents have to be carriers of the genetic mutation associated with Hyperlysinemia, Type 1 (AASS) to have an affected child. So, it may appear that the condition simply "pops up" in families rather than being passed on from generation to generation. When both parents are carriers of Hyperlysinemia, Type 1 (AASS) there is a 25% chance of having an affected child, 50% chance of having a child that is a carrier and 25% chance of having a child that is not a carrier/not affected.
Therefore, it is recommended that patients with Hyperlysinemia, Type 1 (AASS) have their reproductive partner pursue carrier screening to see if they are also carriers for Hyperlysinemia, Type 1 (AASS). If they are, there is a 25% risk of having a child with Hyperlysinemia, Type 1 (AASS) and a 50% risk of having a child who is also a carrier.

Are there different types of Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a genetic condition that is caused by an excess amount of lysine in the body. There is also another type of hyperlysinemia, called hyperlysinemia Type 2 or also known as Saccharopinuria. In hyperlysinemias, a genetic mutation in the AASS gene causes a deficiency of two enzymes, lysine alpha-ketoglutarate reductase and saccharopine dehydrogenase. In hyperlysinemia Type 1 there is a deficiency in both of these enzymes, but in hyperlysinemia Type 2 there is only a deficiency of the saccaropine dehydrogenase. This causes an increased amount of saccharopine in the body, compared to hyperlysinemia Type 1 which causes an increase of serum lysine and saccharopine.
No specific clinical differences have been reported between types 1 and 2, and both of the conditions may include variable neurological and behavioral symptoms. Therefore, clinical outcomes and life expectancies are similar for Hyperlysinemia Type 1 and Hyperlysinemia Type 2. As stated earlier, Hyperlysinemia Type 2 does not cause an increased amount of serum lysine, so a decreased lysine diet would not be used as treatment, unlike in Hyperlysinemia Type 1.
Any other diseases that look a lot like Hyperlysinemia, Type 1 (AASS)?
Hyperlysinemia, Type 1 (AASS) is a metabolic condition that may present with a variable amount of symptoms, including intellectual disability, low muscle tone, behavioral issues, seizures, eye issues, and other neurological and behavioral problems. Although, about half of people with Hyperlysinemia, Type 1 (AASS) show no symptoms of the condition and are usually unaware they have the condition. Although these symptoms are featured in Hyperlysinemia, Type 1 (AASS), they are not exclusively related to this condition. Hyperlysinemia, Type 2 also presents with the same symptoms and it is often difficult to decipher between the two. Genetic testing may be required to make a diagnosis between Hyperlysinemia, Type 1 and 2. Also, many other metabolic genetic conditions and other diseases that present with similar symptoms, such as low muscle tone, intellectual disability and seizures. So, it is important to consult your doctor or geneticist if these symptoms occur.
