Living with Lipoyl transferase 1 deficiency

A very rare inherited metabolic condition that begins in newborns or infants with seizures, delayed development, and muscle tone problems.

Understanding Lipoyl transferase 1 deficiency

Lipoyl transferase 1 deficiency is a very rare inborn error of metabolism (the body has trouble with a chemical process).

It varies a lot between people. It typically begins in newborns or infancy with seizures, delayed development, and muscle tone that may be low or high. Lactic acid builds up in the body. Other features can include vomiting, liver problems, swallowing trouble, and speech problems.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Low muscle tone (hypotonia)
  • Loss of developmental milestones
  • Dystonia (involuntary muscle contractions)
  • Stiff, weak muscles in all limbs (spastic tetraparesis)
  • Shrinking of the cerebellum
  • Enlarged fluid spaces in the brain (ventriculomegaly)

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 LIPT1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    United Mitochondrial Disease Foundation and MitoAction may keep lists of experts for this condition.
