[A report of field survey on acatalasemia and hypocatalasemia in 1965].

The authors reported the results of field survey and family follow-up on acatalasemia and hypocatalasemia during the year of 1965. No hypocatalasemic case was seen in the tests of 2,897 individuals at two places of Japan Proper. And a hypocatalasemic boy was found out among 10,083 children of Miyako Is., Ryukyu. In 1965, ten acatalasemias of six families at various parts in the world were added to the formerly known cases. Consequently, the total of reported acatalasemias amounted to 90 cases of 43 families by the end of 1965.
