We describe two brothers with early onset cerebellar ataxia associated with hypoalbuminemia (EOCAH). Choreo-athetoid movements preceded the cerebellar ataxia, and serum pseudocholinesterase elevation preceded the hypoalbuminemia. The parents are first cousins. Patient 1, the 22-year-old elder brother, developed choreoathetoid movements of the neck and extremities at the age of eighteen months. He later developed slowly progressive cerebellar ataxia with decreased tendon reflexes. The choreoathetoid movements ceased at about 16 years of age. A recent examination revealed cerebellar ataxia, action myoclonus of the neck and upper limbs, diminished tendon reflexes, mild sensory disturbance in the lower extremities, and very slight amyotrophy of the feet. Patient 2, the 18-year-old younger brother, developed choreo-athetoid movements at the age of 6 years, followed by slowly progressive cerebellar ataxia with disminished tendon reflexes. No scoliosis, ECG abnormalities, or edema was detected. Serum biochemistry studies revealed elevated pseudocholinesterase (6,226 to 2,390 IU) in the patient's early teens. Serum albumin levels tended to be low (3.7 to 4.1 g/dl). Serum triglyceride and beta-lipoprotein levels were elevated in the patients' late teens. Genetic studies showed slight linkage of D9S15. The maximum lod score was 0.289 (recombination fraction rate was 0.14).
