title: Trisomy 3p syndrome. Report of a new case, due to a chromosomal insertion.
abstract: A new case of the trisomy 3p syndrome is described. The propositus showed mental and growth retardation and many of the congenital anomalies typical of this syndrome. Chromosome analysis in the propositus revealed an enlarged short arm of chromosome 4. In the mother a similar chromosome 4 was found and, in addition, an abnormal chromosome 3 with a deleted short arm. The karyotype of the mother was interpreted as resulting from a balanced insertional translocation. GTG bands p21 and p22 of chromosome 3 were inserted into the short arm of chromosome 4.
