S. Vickers et al., A MALE WITH A DE-NOVO TRANSLOCATION INVOLVING LOSS OF 15Q11Q13 MATERIAL AND PRADER-WILLI-SYNDROME, Journal of Medical Genetics, 31(6), 1994, pp. 478-481
A male proband is described who carries a de novo translocation betwee
n chromosomes Y and 15 associated with Prader-Willi syndrome. In situ
hybridisation and molecular studies were used to show loss of the pate
rnally derived 15q11q13 region in the translocated chromosome. Lack of
further symptoms indicate that this region was lost with no apparent
deletion of the Y chromosome.
