Acid phosphatase activity in lymphocytes from patients with Spielmeyer-Vogt-Batten's syndrome.

The purpose of the investigation presented was to study whether the lymphocytes from patients with Spielmeyer-Vogt-Batten's syndrome deviate from normal with respect to acid phosphatase activity. The distribution of the activity seems to show that the patients with Spielmeyer-Vogt-Batten's syndrome can be divided into two groups, viz. one in which the values are concentrated around the normal level, and another with increased values.
