Fish-eye disease

Fish-eye disease is an autosomal recessive disorder caused by specific LCAT mutations that merely alter the alpha-LCAT function. The cardinal clinical symptom is eye apocities that resemble boiled fish (that's why the name). Renal involvment as the glomerulosclerosis in Norum disease is less common.

Pathogenesis

Biochemically the enzyme LCAT in fish-eye disease is partially impaired. Only the alpha-LCAT function is altered.
