Breed-typical predispositions
MCOA (multiple congenital ocular anomalies)
Disease →linked to the silver gene (PMEL17): heterozygous animals usually show only cysts, homozygous ones clear malformations. The colour the breed is known for carries the risk — clarify the genotype before mating
Narrow genetic base
the small founder population makes inbreeding management the central breeding topic
Latest findings
Silver gene and MCOA (PMEL17)
2008/2010The ocular anomalies are closely linked to the silver variant; homozygous silver animals are clearly affected, heterozygous ones usually show only iris cysts. Matings of two silver carriers can be deliberately avoided.
