Living with 2-aminoadipic 2-oxoadipic aciduria

A rare metabolic condition affecting how the body breaks down certain amino acids; some people have no symptoms.

Understanding 2-aminoadipic 2-oxoadipic aciduria

2-aminoadipic 2-oxoadipic aciduria is a rare condition that affects how the body breaks down the amino acids lysine and tryptophan.

It is found by testing, which shows certain acids in the urine. Some people have low muscle tone, developmental delay, learning challenges, poor balance (ataxia), epilepsy, or behavior concerns such as ADHD. Many people with the test finding have no symptoms at all, so how much it matters is unclear. GARD lists onset as infant and child.

Signs & symptoms

GARD lists no common symptoms. These are listed as less common, and many people have none:

  • Delayed speech and language
  • Global developmental delay
  • Intellectual disability
  • Attention deficit
  • Autism
  • Small head size

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists.

  3. Consider genetic testing

    Changes in DHTKD1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Does my child's test result need follow-up or monitoring?
Is genetic testing of the DHTKD1 gene helpful for our family?
Which development or behavior checks should we plan?

Quick facts

InheritanceAutosomal Recessive
GenesDHTKD1

Changes in the DHTKD1 gene cause this condition. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
