(Equine SCID)

  • Autosomal recessive
  • Occurs in 2-3% of Arabian foals
  • Defect in DNA-dependent protein kinase gene
    • Gene codes for a DNA repair enzyme involved in V(D)J recombination for antigen receptors of lymphocytes (e.g. Ig and TCR)
  • No functional B cells or T cells
  • Foals develop infections (usually around 8 weeks of age as maternal antibody in colostrum wanes around this time)
  • Foals usually die from bronchopneumonia
