Living with Hemolytic anemia due to adenylate kinase deficiency

A rare inherited blood condition in which red blood cells break down early, causing long-term anemia.

Understanding Hemolytic anemia due to adenylate kinase deficiency

Hemolytic anemia due to adenylate kinase deficiency is a rare inherited condition in which red blood cells break down faster than normal.

The anemia is long-lasting and ranges from moderate to severe. Some people need regular blood transfusions or surgery to remove the spleen (splenectomy). Some also have delays in movement and thinking skills (psychomotor impairment). It starts between birth and childhood.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on the summary, it can include:

  • Long-lasting anemia from red blood cell breakdown
  • Need for regular blood transfusions in some people
  • Delays in movement and thinking skills in some people

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 blood and bone marrow specialists and genetic specialists.

  3. Consider genetic testing

    Changes in AK1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
How severe is the anemia, and how will it be monitored?
When might transfusions or spleen removal be considered?

Quick facts

Symptoms usually startfrom Birth to Childhood
InheritanceAutosomal Recessive
GenesAK1

It is caused by changes in the AK1 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
