Adenosine Deaminase (Ada) Deficiency

ADA Deficiency is characterized by severe combined immunodeficiency also known as SCID. The deficiency is caused by a single point mutation in the ADA gene. Individuals with ADA are prone to all sorts of infections.

Medical Condition
  • Bacterial, Viral & Fungal Infections
  • Chronic diarrhea
  • Pneumonia
  • Skin rashes & allergy
  • Delayed development
  • Chronic lung disease
  • Malnutrition
Genetic Changes
  • ADA gene provides instructions for producing the Adenosine deaminase enzyme
  • Adenosine Deaminase breaks down a molecule called deoxyadenosine which can be toxic to white blood cells (WBC) if not controlled
  • Mutation of ADA gene causes buildup of the deoxyadenosine which leads to destruction of the WBCs

No specific treatment as it is a genetic disorder with high morbidity.

  • Bone Marrow transplantation
  • Blood transfusion
  • Enzyme replacement therapy
  • Gene therapy

  • Genetic screening can identify single gene disorders
  • Early prognosis can prevent such diseases
  • Remedial & personalized medicine can change the outcome
  • Doctors can suggest alternatives for couples planning pregnancy
