β¦ Synopsis
A 29-year-old male with Angelman syndrome and an unbalanced reciprocal translocation, 45,XY,-8, -15,+der(8),t(8;15)(p23.3;qll)pat, was evaluated with DNA studies. These showed the underlying mechanism to be paternal uniparental disomy. This is the second case reported of Angelman syndrome that has resulted from a familial unbalanced reciprocal translocation.

A balanced Robertsonian translocation 45,XY,t(15q15q) was detected in a patient with mental retardation, microcephaly, and hypertonia. Deletion of the 15qllq13 region was unlikely based on fluorescence in situ hybridization studies that revealed hybridization of appropriate DNA probes to both arms o
Maternal uniparental disomy (UPD) for chromosome 15 is responsible for an estimated 30% of cases of Prader-Willi syndrome (PWS). We report on an unusual case of maternal disomy 15 in PWS that is most consistent with adjacent-1 segregation of a paternal t(3;15)(p25;q11.2) with simultaneous maternal m
A boy with both Down's and Sturge-Weber's syndrome was found to have a partial trisomy 21 as a consequence of a familial translocation t(3p-;21q+) which is not reciprocal. Judging from the structure of the involved chromosomes studied by banding and photometrical techniques, the loss of relatively l
