Elevated Frequency and Allelic Heterogeneity of Congenital Nephrotic Syndrome, Finnish Type, in the Old Order Mennonites

We are very indebted to the members of the numerous families with nephrotic syndrome, for sharing information and donating tissue samples; without these families this work would have been impossible. We gratefully acknowledge the superb assistance of Jennifer Scott, for family studies; Kimberly Bentley, Andrew Wong, and Gilbert Wong, for DNA sequencing and technical assistance; and Carl Kashuk, for informatics. This work was supported by National Institutes of Health grant HD28088 to A.C.
