Presentation on SCID

Severe Combined Immune Deficiency

  • SCID is a group of very rare—and potentially fatal—inherited disordersof the immune system

What other names are there for the disorder?

  • Alymphocytosis
  • Glanzmann-Rinker Syndrome
  • Severe Mixed Immunodeficiency
  • Thymic Alymphoplasia
  • Bubble Boy Disease

What causes the disorder?

  • Mutation
  • Depending on the type of SCID, B cells and NK cells can also be affected.
  • Other forms of SCID are caused by a deficiency of the enzyme adenosine deaminase (ADA) and a variety of other genetic defects
  • SCID is caused by a genetic defect that affects the function of T cells

How is it inherited?

  • The condition is inherited in an X-linked recessive pattern.

What gene or chromosome is affected by this disorder?

  • X-Chromosome

How is the disease diagnosed?

  • The most common screening methods are an immune function test
  • a blood test that detects low white blood cell counts, as well as low levels of immune cells 

Are there prenatal tests for this disorder, if so what are they?

  • By removing and testing cells from the placenta
  • By removing and testing a sample of the fluid surrounding the baby.

What is the life expectancy of someone with the disease?

  • Children with the disease aren't likely to live past age 2.

What are the symptoms, side effects or harm does it cause on the human body?

  • frequent and often very severe respiratory infections
  • SCID in infants include poor growth
  • recurrent thrush in the mouth
  • Often, SCID is associated with recurrent viral infections and causes several hospitalizations 
  • pneumocystis pneumonia

Can anyone be a candidate for the disorder?

  • When a gene is located on the X chromosome, males are more often affected than females
  •  Males do not have a second X chromosome to compensate for the defective one
  • About 1 out of every 100,000 babies is born with SCIDAdd another list item here

Are there any treatments, medications, or therapies

  • The most effective treatment is a bone marrow transplant
  • Medications – especially antibiotic, antifungal, and antiviral medications to treat or prevent active infections
  • Add aAvoiding exposure to infections, especially ones that may be difficult to eradicate, such as chicken poxnother list item here
  • Use immunoglobulin supplementation (IVIg)
  • Add anoEnzyme replacement therapyther list item here

Could this disorder have been prevented?

  • No, this disorder can not be prevented
  • Yes there is genetic testing to determine if you are a carrier of the trait

Can this individual have children in the future?

  • Yes, can have children
  • Yes, can be passed to their children

Are there any cures?

  • Yes, if diagnosed early
