A family with dominantly inherited aniridia in three generations is presented. All three patients had an apparently balanced chromosome translocation t(4;11)(q22;p13). The patients were otherwise clinically normal and without signs of Wilms' tumor; their erythrocyte catalase activities were within t

✦ Synopsis
A patient is reported with del11p13, low catalase level, nephroblastoma, chordee and cryptorchidism, no evident mental retardation, and with normal irides. This unique observation suggests the following order of loci in 11p13, from centromere to telomere: catalase, Wilms tumor, aniridia. The chromosomal origin of nephroblastoma may be more frequent than estimated on the basis of its association with aniridia.

A severely retarded child with multiple malformations was found to present a mosaic karyotype 46,XX, - 13,+t(13;13)(p11;q11)/46,XX,del(13)(p11), which probably originated as the result of a de novo 13/13 translocation in a parental gamete, followed by postzygotic fission of the translocation chromos
