Clinical, histopathological, and biochemical findings in Fabry's disease. A case report and family study.

An extensive enzymatic and morphological study was performed in a 38-year-old patient with Fabry's disease (FD). The quantitative evaluation of the enzyme alpha-galactosidase was shown to be important in identifying the genetic distribution of FD in the family tree of the patient under study. An enzymatic activity less than 0.5 nanomole/hr/10(6) cells and ranging from 2.2 to 1.1 nanomoles/hr/10(6) cells was found in the affected males and the heterozygous females, respectively. alpha-galactosidase activity in the patient's leukocytes correlates well with the histopathological findings of the kidney and skin biopsy specimens, thus demonstrating the need for both of these special examinations for a correct diagnosis of FD.

HLA antigens and insulin dependent diabetes mellitus. A family study.

Sixteen insulin dependent diabetic patients (age at onset less than 35 years) and their families were tissue typed for HLA antigens. Glucose tolerance of relatives was also tested. Among diabetic patients two HLA antigens were found with increased frequency: B8 (31 percent, control 15 percent) and Bw35 (38 percent, control 23 percent). Among normal relatives B8 and Bw35 had the same frequency as the control group. Bw15 frequency was not increased in either group. In relatives, no correlation between HLA antigens (B8 or Bw35) and abnormal glucose tolerance, obesity and over-weight at birth was found. Present data confirm previous reports of high B8 frequency in early onset diabetic patients, but fail to demonstrate a raised frequency of abnormal glucose tolerance among relatives bearing B8 (or, in our cases, Bw35). B8 may be considered a genetic indicator for susceptibility to juvenile diabetes. On the basis of present results in families, however non genetic factors clearly also play a determinant role. Furthermore, that diabetogenesis arises from a link between Ir-genes and HLA-B8 antigen should only be considered a suggestive hypothesis.
