Autoimmune Lymphoproliferative Syndrome

(ONLINE PRICE)

Test Overview:

Inheritance: ALPS is an autosomal recessive genetic disorder, meaning affected cats have two copies of the mutant gene, while carriers have only one copy and are clinically healthy but can pass the mutation to offspring. Carrier Breeding: Carrier cats (with one copy of the mutation) can be safely bred only with genetically clear cats (with no copies of the mutation). About 50% of offspring from a carrier × clear mating will be carriers, while 50% will be clear. Carrier × carrier matings are not recommended because they have a 25% chance of producing affected kittens, 50% chance of producing carriers, and 25% chance of clear kittens.
