Alpha-mannosidosis in a Persian cat.

P F Jezyk, M E Haskins, L R Newman

    Journal of the American Veterinary Medical Association
    |December 1, 1986
    PubMed
    Summary

    Alpha-mannosidosis, a rare inherited enzyme deficiency, caused severe health issues in a Persian cat, leading to its euthanasia. This lysosomal storage disorder highlights the need for understanding genetic diseases in felines.

    Area of Science:

    • Veterinary Medicine
    • Genetics
    • Biochemistry

    Background:

    • Alpha-mannosidosis is an inherited lysosomal storage disorder.
    • It results from a deficiency in the enzyme alpha-mannosidase.
    • This deficiency leads to the accumulation of oligosaccharides in cells.

    Observation:

    • A Persian cat presented with clinical signs consistent with alpha-mannosidosis.
    • Observed abnormalities included growth retardation, enlarged liver (hepatomegaly), and eye problems.
    • Neurologic dysfunction was also a prominent feature.

    Findings:

    • The cat exhibited a severe, progressive form of alpha-mannosidosis.
    • The condition was diagnosed as an autosomal recessive genetic disorder.
    • The affected feline was euthanatized at five months of age due to disease severity.

    Implications:

    • This case underscores the impact of genetic enzyme deficiencies in domestic animals.
    • Understanding lysosomal storage disorders is crucial for feline veterinary care.
    • Further research into alpha-mannosidosis can aid in diagnosis and potential therapies for affected cats.
