BAER (Brainstem Auditory Evoked Response)
Deafness is a trait that can appear in homozygous white cats of all breeds. It also occurs more rarely in cats with "high white" and/or van patterns. Many theories attempt to explain deafness inheritance, but so far no one theory adequately accounts for all incidences. The brainstem auditory evoked response (BAER) test measures responses in brain waves that are stimulated by a clicking sound to check the central auditory (hearing) pathways of the brainstem. Further HCM resources are available here.

GSD-IV (Glycogen Storage Disease IV)
Glycogen storage disease type IV is an inherited disorder of the Norwegian Forest Cat where an essential enzyme required to produce glucose (energy) is deficient. Afflicted kittens are usually stillborn but may develop normally until 4-5 months of age
before suffering terminal neuromuscular degeneration. The disorder is autosomal recessive; both parents must be carriers of
the trait in order for offspring to be affected. Further GSD-IV information can be found here.

HCM (Hypertrophic Cardiomyopathy)
Hypertrophic Cardiomyopathy is a
terminal condition where the heart muscle enlarges and thickens progressively over time. It can be a cause of sudden death,
and symptoms may be mild or nonexistent. The disease is caused by mutations in several genes and passed down to offspring by autosomal dominant inheritance.
Any cat regardless of breed can be afflicted with the disease. Further HCM resources are available here.
Please Note: We are not accepting DNA test results at this time; there is currently no approved
DNA test for HCM in Norwegian Forest Cats. Only ultrasound results are posted on this site.

PKD (Polycystic Kidney Disease)
Polycystic kidney disease is an inherited disease
where cysts are present on the kidney from birth, progressively destroying the organ and causing terminal renal failure. Ultrasound
can detect PKD as early as 10 months of age and is 98% accurate; a DNA test has been developed for cats
stemming from Persian/Exotic lines, but the disease has been seen in other breeds and non-pedigreed cats.
Further PKD resources are available here.
Please Note: We are not accepting DNA test results at this time; there is currently no approved
DNA test for PKD in Norwegian Forest Cats. Only ultrasound results are posted on this site.
