title: 47,XY,+der(11;22)(q23;q12) following balanced translocation t(11;22)(q23;q12)mat. Remarks on the problem of trisomy 22.
abstract: Report of a supernumerary extra chromosome der(11;22)(q23;q12) resulting from a balanced translocation in the mother. The propositus suffers from mental deficiency, deafness and extreme muscular weakness and exhibits cleft palate, a labial lymphangioma and an atrial septum defect. Since the features of partial trisomy 11q23 frequently associated with a translocation t(11q;22q) bear similarities with the cases of so called trisomy 22 one might conjecture that some of these observations are in fact products of translocations including partial 11q.
