How is severe combined immunodeficiency inhereited?

Forms of SCID. The original question asked about scid (severe combined immunedeficiency), not cvid (common variable immunodeficiency). There are several types of scid. Scid can be transmitted by both x-linked, and autosomal recessive patterns. Patients with scid have a defect in their immune system that makes them vulnerable to deadly infections. See an immunologist if you suspect scid.
CVID. Also use online resources to read more and educate yourself and your family. Go to www.Immunedeficiency.Org and the jeffrey mofell foundation to learn and read more. It really helps.
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.
