Uveal colobomata and Klinefelter syndrome.
Most multiple congenital abnormality syndromes associated with uveal colobomata have their origins dating from before intrauterine development. Causative genetic and chromosomal influences were reviewed (James, Karseras, and Wybar, 1974), but associated abnornalities of the sex chromosomes were not observed in their series and are a rare occurrence in the literature. It is of interest therefore...
متن کاملUveal coloboma and true Klinefelter syndrome.
The clinical features of 'Klinefelter' syndrome were first described by Klinefelter, Reifenstein, and Albright (1942). The true Klinefelter syndrome is chromatin-positive and is due to X chromosome polysomy, most frequently 47,XXY (Jacobs and Strong, 1959), but karyotypes with one or more X's or Y's additional to the XXY formula, such as 48,XXXY, 49,XXXXY, and mosaicisms of XXY with other stem-...
متن کاملAn autosomal dominant syndrome of uveal colobomata, cleft lip and palate, and mental retardation.
This report details a family in whom there is autosomal dominantly inherited uveal colobomata, associated eye defects, and cleft lip and palate occurring in twelve subjects over three generations. Considerable variability in expression of the gene is apparent, uveal colobomata being the most constant feature, and the full syndrome probably includes mental retardation of varying degree. The poss...
متن کاملColobomata associated with Noonan's syndrome.
A patient with Noonan's syndrome and fundal colobomata in both eyes is described. To our knowledge, this is the first report of the association of colobomata with Noonan's syndrome. Although the patient had poor sight since early childhood and dyspnea on exertion as a teenager, the diagnosis of Noonan's syndrome was not made until early adulthood. We hope this report will encourage recognition ...
متن کاملKlinefelter syndrome
Some males with Klinefelter syndrome have the extra X chromosome only in some of their cells (mosaic Klinefelter syndrome). In addition, 46,XX males also exist and it is caused by translocation of Y material including sex determining region (SRY) to the X chromosome during paternal meiosis. Formal cytogenetic analysis is necessary to make a definite diagnosis, and more obvious differences in ph...
