About the test

This DNA test detects the Pattern 1 (PATN1) mutation, a dominant genetic variant that influences the extent of white spotting in horses carrying the Leopard Complex (LP) gene.

PATN1 is one of the major modifier genes responsible for the characteristic white coat patterns seen in Appaloosa and other spotted horse breeds.

Why test?

Testing is recommended to:

Confirm the presence of the PATN1 spotting modifier.
Predict the likelihood of extensive white spotting in horses carrying the Leopard Complex (LP) gene.
Support breeding decisions for Appaloosa and other spotted coat patterns.
Differentiate horses carrying PATN1 from those with other white patterning genes.

Results

The DNA test verifies the presence of the dominant (PATN1) mutation and presents results as one of the following:

N/ - Negative for PATN1.Absence of the dominante PATN1 gene - non spotted horse.
PATN1/N - Positive heterozygous for PATN1 (Dominant). Presence of one copy of the dominant PATN1 gene responsible spotted coat. The horse can pass the PATN1 variant to 50% of their progeny when bred.
PATN1/ -Positive homozygous for PATN1 (Dominant). Presence of two copies of the dominant PATN1 gene responsible for spotted coat.The horse will pass the PATN1 gene to 100% of its offspring.

Additional information

Pattern 1 (PATN1) is a dominant modifier gene that acts together with the Leopard Complex (LP) gene to increase the amount of white spotting on the horse's coat.

PATN1 alone does not produce a spotted coat. Its effect is expressed only in horses that also carry the LP gene. Horses carrying both LP and PATN1 typically exhibit larger white blanket patterns or extensive leopard spotting compared with horses carrying LP alone.

Because coat pattern expression is influenced by multiple genes, the amount and distribution of white can vary considerably between individuals.

Testing for PATN1, together with the Leopard Complex (LP) test, provides breeders with the most accurate prediction of spotted coat inheritance.

FAQs

Which samples are accepted?

The test can be performed using 20–30 hair roots or 5 mL of blood collected in a K3 EDTA tube.

Does PATN1 cause spotting by itself?

No. PATN1 modifies the expression of the Leopard Complex (LP) gene but does not produce a spotted coat on its own.

Should this test be performed with another genetic test?

Yes. For the most accurate prediction of coat pattern, PATN1 testing is recommended together with the Leopard Complex (LP) DNA test.

Can a horse without visible spotting carry PATN1?

Yes. Horses without the LP gene may carry PATN1 without expressing its characteristic white spotting pattern.

When will I receive my results?

Results are available within 2 to 5 working days after sample arrival at the laboratory.
