    Abstract

    An unbalanced translocation of a portion of the long arm of chromosome 21 to the short arm of chromosome 4 resulted in a partial deletion of chromosome 21 (pter----q21.05) and in the loss of the telomere of 4p. The phenotype of the child included asymmetrical facies, microcephaly, short stature, hypotonia, and psychomotor retardation associated with frequent infections. Normal SOD-1 activity in red blood cells and fibroblasts and normal cystathionine beta synthase activity in fibroblasts suggest that these gene loci are distal to 21q21.05.
