Summary

We studied the occurrence of renal disease by measuring serum creatinine and urine protein concentrations in the diabetic members of 316 Pima Indian families with Type 2 (non-insulin-dependent) diabetes in two successive generations to determine if diabetic renal disease aggregates in families. After adjustment for sex and other risk factors, proteinuria occurred among 14.3% of the diabetic offspring if neither parent had proteinuria, 22.9% if at least one diabetic parent had proteinuria, and 45.9% if both parents had diabetes and proteinuria. Among male offspring, an elevated serum creatinine concentration (≥177 μmol/l) was present in 11.7% if the parent had an elevated creatinine and in 1.5% if the parent did not. Thus, proteinuria and high serum creatinine aggregated in diabetic families, suggesting that susceptibility to renal disease is inherited independently of diabetes.
