Leopard complex

Characteristic and trait of inheritance

A single autosomal dominant gene, leopard complex (LP), is responsible for different spotting patterns while modifier genes are thought to play a role in determining the amount of white patterning that is inherited. These patterns are called from lightest to darkest: „few spot leopard“, „leopard“, „snowcap blanket“, „blanket with spots“, „varnish roan (marble)“, „snowflake“, „frosted“, „speckled“ and „mottled“.
Homozygosity for LP (LP/LP) is directly associated with congenital stationary night blindness (CSNB) in Appaloosa horses. Heterozygous carriers (LP/lp) are not affected. CSNB is characterized by impaired vision in dark conditions, and is present at birth.


All breed

Test duration

1-2 weeks after arrival of the sample in the lab


The DNA test is performed out of EDTA blood or or 20-30 hair roots from mane or tail. Test kits can be ordered free of charge. (order-form). If hair is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer.
Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
