Species-specific name: Combined immunodeficiency disease

History: This disorder was first described by McGuire and Poppie (1973).

Mapping: Using 23 microsatellite markers on a carrier stallion and 19 affected offspring, Bailey et al. (1997) showed linkage of this disorder to the markers HTG8 and HTG4. Knowing that the DNAPK gene had recently been implicated in mouse SCID (Blunt et al.,(1996) PNAS 93: 10285-90), these authors then used a somatic cell hybrid panel to show that the equine DNA-PK gene is syntenic with those same two microsatellite markers, thereby implicating DNAPK as a very strong candidate gene for equine SCID. By FISH analysis, they also showed that this gene physically maps to horse chromosome ECA9p12.

Molecular basis: After many years of frustration for many researchers, the molecular basis of SCID in horses was discovered by Shin et al. (1997), who used the comparative candidate-gene approach (based on work with SCID mice, in which Blunt et al., (1996; PNAS 93: 10285-90) had shown a mutation in the DNAPK, encoding DNA-dependent protein kinase catalytic subunit, to be causal). By sequencing the equine homologue of DNAPK, Shin et al. (1997) showed that SCID in horses is due to a 5bp deletion giving rise to a frameshift in that gene, resulting in the lack of full-length kinase, and absence of kinase activity. The DNAPK gene was previously called DNA-PKcs; it is now called PRKDC (protein kinase, DNA-activated, catalytic polypeptide).
