SCID stands for Severe Combined Immune Deficiency. It is an autosomal recessive gene in Arabian horses that causes a foal's immune system to not develop. It is uniformly fatal within 12 months.
Technically horses with SCID, specifically Arabians are not born with a virus. SCID is actually a genetic defect on chromosome #9. The answer of no immune system is correct in a SCID horse with this autosomal recessive defect can not produce T and B-lymphocytes, which are part of a healthy immune system. An SCID foal will die within weeks but most likely before five months of age, because they can not fight off infection. Infection can come from: bacteria, viruses, fungus. With a careful breeding plan, the birth of an SCID foal can be prevented. no immune systym
