OMIA 000220-9615 : Severe combined immunodeficiency disease, autosomal in Canis lupus familiaris

In other species: horse

Possibly relevant human trait(s) and/or gene(s) (MIM number): 600899

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2002

Species-specific name: Combined immunodeficiency disease

Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Ding et al. (2002) identied a causal mutation in the canine DNA-PKcs gene as "a point mutation [which] results in a stop codon at nucleotide 10,828 and premature termination at a position 517 amino acids before the normal C terminus resulting in a functionally null allele". The gene is now called PRKDC in dogs and DNAPK in horses (in which the same disorder is due to mutations in the homologous gene).

Associated gene:

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
