Clinical diagnosis of the disease is not straightforward as the symptoms, such as raised temperature, respiratory complications and diarrhoea, are typical of new-born foals with a range of infections.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eFoals affected by SCID always die from the disorder within the first six months of life. This happens regardless of the level of veterinary care. SCID is therefore a distressing condition for the effected animal and the owners or caregivers, and results in financial loss due to dead foals and veterinary expenses.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eThe disorder is recessive, which means that a horse must be homozygous positive or have two copies of the defective gene to suffer from the disease. Consequently both the sire and the dam must possess at least one copy of the mutated gene in order for the offspring to be afflicted. Offspring born with one copy of the defective gene and one non-defective copy are considered a carrier and have a 50% chance of passing the defective gene on.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eA number of studies have attempted to estimate the frequency of SCID carriers in the Arab horse population.
