Lysosomal storage diseases in livestock

Area of Science:

• Veterinary Medicine
• Genetics
• Toxicology

Background:

• Lysosomal storage diseases (LSDs) are a group of inherited or acquired metabolic disorders.
• Inherited LSDs are typically autosomal, with heterozygotes showing intermediate enzyme activity.
• Artificial breeding technologies have facilitated the spread of genetic LSDs in cattle populations.

Purpose of the Study:

• To summarize the causes and transmission of lysosomal storage diseases in livestock.
• To differentiate between inherited and acquired forms of LSDs.
• To highlight the impact of breeding practices and environmental factors on LSD prevalence.

Main Methods:

• Review of existing literature on lysosomal storage diseases in veterinary medicine.
• Analysis of inheritance patterns for genetic LSDs.
• Identification of common etiological agents for acquired LSDs, particularly plant toxins.

Main Results:

• Inherited LSDs are often autosomal recessive, detectable in heterozygotes through enzyme assays.
• The founder effect, amplified by artificial breeding, significantly contributes to the prevalence of genetic LSDs in cattle.
• Acquired LSDs in livestock are predominantly caused by the ingestion of toxic plants.

Conclusions:

• Understanding the distinct origins of inherited and acquired LSDs is crucial for effective disease management in livestock.
• Genetic screening and responsible breeding practices are essential to control inherited LSDs in cattle.
• Awareness of plant toxicity is vital for preventing acquired LSDs in various livestock species.
