Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: no

Cross-species summary: Developmental failure of cleavage of the forebrain (prosencephalon); with a deficit in midline facial development, and with cyclopia (see MIA 000249) in the severe form.

Inheritance: Keting et al. (2016) provided evidence consistent with autosomal recessive inheritance.

Clinical features: "Ventriculomegaly with frequent concomitant supratentorial interhemispheric, communicating ventricular type-1b cysts and multiple midline and callosal malformations were detected in all cats displaying neurologic signs" (Keating et al., 2016)

Breed: Toyger.
