title: Properdin factor B (Bf) types in schizophrenia.
abstract: The phenotype frequencies of properdin factor B (Bf) were studied in patients with (n = 47) and without (n = 66) a family history of schizophrenia and in controls. In patients with a family history of schizophrenia, a significant decrease of the FS type was found. No significant difference was found between patients without a family history of schizophrenia and controls.
