Abstract:
A mentally handicapped 3 year old child with cystinuria is presented. Routine chromosomal analysis showed an apparently balanced de novo translocation in the child with breakpoints 14q22 and 20p13. Family studies suggested that the child is a type I/type II compound heterozygote for cystinuria. This translocation may indicate a possible locus for the gene for cystinuria.
