Amelogenesis Imperfecta (Akita Type)

Test Overview:

The study revealed two new canine AI variants in ENAM and ACP4 genes. Both of these genes play a significant role in the secretory stage of amelogenesis and their defects lead to enamel hypoplasia.


Dental - Associated with the teeth and associated structures



Variant Detected:

c.1189dupG p.(Ala397Glyfs)


Moderate-Severe. This is a disease with significant welfare impact on the affected animal, in terms of clinical signs and generally reduced life expectancy.

Mode of Inheritance:

Autosomal Recessive
