We are taking an Easter break between the Easter and ANZAC day long weekends. You can still place orders now, and also while we are on break. If we we receive but don't finish testing your samples before Easter they will be at the top of our list when we re-open.
CNS atrophy with cerebellar ataxia (CACA)
Summary
Cerebellar ataxia (CA) is a movement disorder that appears as a lack of balance and coordination often accompanied by a tremor. In some cases this seems to be accompanied by a loss of proprioception (the ability to sense location and action in the body).
This particular type of CA can be very severe, and presents in puppies as young as 2 weeks old. It is associated with a genomic deletion that removes the SELENOP gene. This gene is required for healthy normal selenium transport in the brain and spinal cord as well as elsewhere in the body, and its loss causes CNS atrophy and CA (hence the CACA acronym).
CACA requires both parents to pass on the genomic deletion encompassing the SELENOP gene. CACA affects both males and females equally. Carriers (dogs with a CACA n genotype) won't have CACA but can pass the gene on to offspring.
