Breeds Affected: Pug

Samples Accepted: Blood, Buccal Swab

Disease Information: May-Hegglin Anomaly is a rare disorder of platelet formation (including macrothrombocytosis and thrombocytopenia) which may be mistaken for immune-mediated thrombocytopenia.

Inheritance Information: May-Hegglin Anomaly is believed to be autosomal dominant, meaning that animals with one copy of this allele will be affected. 50% of their offspring will also be affected.

The possible genotypes are:
n/n The dog is normal, and cannot produce MHA-affected offspring.

n/MHA The dog is affected with MHA, and 50% of the offspring will be affected.

MHA/MHA The dog is affected with MHA, and 100% of the offspring will also be affected.

– Affected animals (n/MHA, MHA/MHA) should not be used for breeding.

Test Information: This mutation test identifies a single base change in the MYH9 gene.
