Inherited: Severe combined immunodeficiency (scid) is a genetic condition. The defective gene is transmitted from parents to their children, though many times is an 'accident of nature' that starts with the affected child. Genetic counseling is helpful.
Dr. David Rosenthal
Allergy and Immunology 21 years experience
Genetically: There are different inheritance patterns. If you have severe combined immunodeficiency and are planning on having a child, seek the help of an immunodeficiency specialist and a genetic counselor.

How is severe combined immunodeficiency inhereited?

Two major forms: The most common form is x-linked, that can be sporadic (no inheritance), but often because the mother is a 'carrier' of the defective gene. Only males are affected. Sons of a carrier have a 50% chance to inherit the defective gene and develop disease, daughters have 50% of inherit the defective gene and be 'carriers'. The other major form is autosomal recessive. Genetic counseling is recommended.

Depends: Scid screening should be done very early in life -- within the first few days. This test is clinically available and looks for, or the lack of, trec's -- which are parts of dna that should be present if immune system is developing properly. If scid screen is abnl and suggests scid the immunophenotyping will be done to confirm screen and further identify genetic defect.
