Familial partial trisomy 8p without dysmorphic features and only mild mental retardation.
We report on a mother and her two sons who had a direct duplication of chromosome region 8p22-8p23.1 without dysmorphic features and only mild mental retardation. The patients have been studied using G banding, chromosome painting, and FISH using cosmid probes specific for the region 8p23.1-8pter. Comparison of the phenotypes of our patients and ofpublished patients with an inversion duplicatio...
متن کاملPartial monosomy 8p with minimal dysmorphic signs.
A female patient with a 46,XX,del(8)(p23----pter) karyotype is presented. She was mentally retarded and showed a few dysmorphic features. Her red cell glutathione reductase level was within normal limits. This terminal deletion, on the short arm of chromosome 8, appears to be the smallest segment hitherto reported.
متن کاملInv dup (15) with mental retardation but few dysmorphic features.
We report a Scottish child with inv dup (15) and compare the clinical features with those of previously reported cases. Since the first report by Parker and Alfi in 1972, there have been 44 reports of patients with confirmed or suspected inv dup (15). The extra chromosomal material has been variously described, but in all cases there appears to be an additional G group sized chromosome in which...
متن کاملTetrasomy 21pterRq21.2 in a male infant without typical Down’s syndrome dysmorphic features but moderate mental retardation
D own’s syndrome is caused by trisomy of chromosome 21. This invariably results in cognitive impairment, hypotonia, and characteristic phenotypic features such as flat facies, upslanting palpebral fissures, and inner epicanthal folds, and variations in digits and the ridge formation on hands and feet. Furthermore, trisomy 21 is a risk factor for congenital heart disease, Hirschsprung’s disease,...

Four children in the same family have 47, +der (14), t(9;14) (p24;q21). Their mothers are sisters with 46,XX,t(9;14) (p24;q21). Clinical features of the children are similar to those of others reported to have partial 14 trisomy.
