Prader-Willi syndrome in siblings, due to unbalanced translocation between chromosomes 15 and 22.
نویسندگان
چکیده
In a family in which the father carried a balanced translocation between chromosomes 15 and 22 two of his children had Prader-Willi syndrome and an unbalanced chromosome complement, having lost the proximal bands from the long arm of chromosome 15. His four other surviving children were normal but carried a balanced translocation.

متن کاملPrader-Willi syndrome with an unusually large 15q deletion due to an unbalanced translocation t(4;15).
Prader-Willi syndrome (PWS) is a neurobehavioral disorder caused by deletions in the 15q11-q13 region, by maternal uniparental disomy of chromosome 15 or by imprinting defects. Structural rearrangements of chromosome 15 have been described in about 5% of the patients with typical or atypical PWS phenotype. An 8-year-old boy with a clinical diagnosis of PWS, severe neurodevelopmental delay, abse...
متن کاملPrader-Willi syndrome resulting from an unbalanced translocation: characterization by array comparative genomic hybridization.
Prader-Willi syndrome (PWS) is caused by lack of expression of paternally inherited genes on chromosome 15q11-->15q13. Most cases result from microdeletions in proximal chromosome 15q. The remainder results from maternal uniparental disomy of chromosome 15, imprinting center defects, and rarely from balanced or unbalanced chromosome rearrangements involving chromosome 15. We report a patient wi...

Child with PWS at the age between 2 and 3 years becomes constantly hungry and if the diet is not controlled,...
متن کاملThe Prader-Willi syndrome with a 15/15 translocation. Case report and review of the literature.
A case, diagnosed clinically as the Prader-Willi syndrome, was shown by Giemsa banding, to have a 15/15 chromosome translocation. A review of the literature indicates that such a translocation has only been described once before, in a normal woman, but that chromosme abnormalities in the Prader-Willi syndrome most commonly involve the D group. The significance of this would be clarified by spec...
