Congenital Keratoconjunctivitis Sicca and Ichthyosiform Dermatosis
Congenital Keratoconjunctivitis Sicca and Ichthyosiform Dermatosis (CKCSID) is an inherited disorder that affects the Cavalier King Charles Spaniel. It is characterized by dry eyes due to tear production failure and skin abnormalities that cause scaliness and itchiness. These conditions are present at birth and autosomal recessive, requiring two copies of the same mutation in the FAM83H-chr gene for the disease to manifest.
