A 1-year-old male infant was found to have a de novo unbalanced translocation, resulting in trisomy for a portion of the short arm of chromosome 3, i.e. 46,XY,der(7)t(3;7) (p24.1;p22). Previous cases with a so-called "trisomy 3p syndrome" were evaluated by GTG banding, while we attempted to characterize the present case by the FISH-technique. The major clinical features included: dysmorphic ears, decreased muscle tone and seizure episodes associated with fever, which are concordant with "trisomy 3p syndrome". The most common malformations of trisomy 3p syndrome are: psychomotor and mental retardation, short neck, hypertelorism/telecanthus and congenital heart defects. Predominantly, the 3p trisomies have been maternally derived and the major mechanism of inheritance is due to a malsegregation of the chromosomes that are involved in a parental balanced translocation. A review of 44 cases from 35 studies revealed that the clinical manifestations have been quite varied, depending upon the amount of 3p2 material in the trisomic state, but interestingly a recognizable pattern of features was obvious in those cases whose cytogenetic findings and clinical histories were known.
