We report an extremely rare case of Turner syndrome mosaicism in a 30-year-old woman. At least 100 metaphases were observed and analyzed through GTG banding with over 550 band resolutions observed. G-banded chromosome analysis revealed a mosaic female karyotype involving 3 different cell lines. One cell line (90% of the analyzed metaphases) presented monosomy X, while 6% of the cells showed tri...

abstract  background: mosaic form of turner syndrome that represented by two or more  cell lines in an affected individual, often has limitation for detection with classical  cytogenetic methods. the present study was carried out to compare the efficiency of  interphase fluorescence in situ hybridisation (fish) and cytogenetic techniques in  detection of mosaic form of turner syndrome.  methods...

the genus onobrychis belongs to family fabaceae and has about 130 species throughout the world. onobrychis sect. hymenobrychis with nearly 14 species in iran is one of the important sections of the genus. the chromosome number and meiotic behaviour were studied in two populations of onobrychis chorassanica belonging to this section native to iran. this report is the first cytogenetic analysis o...

in this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of diplotaxis harra (forssk.) boiss. this is the first cytogenetic report of the taxon. the two of the populations scored now from regions of the central showed aneuploid (x = 14) meiotic chromosome count and one of the populations studied from the existed a...

in this study the original mitotic chromosome counts are presented for 5 onobrychis species of o. sect. onobrychis in iran, 2n = 2x = 14 for o. persica, 2n = 4x = 28 for o. viciifolia, 2n = 4x = 28 for o. altissima, 2n = 2x = 14 for o. shahpurensis and 2n = 2x = 14 for o. sosnovskyi. the basic chromosome numbers of all studied taxa are consistent with the proposed base number of x = 7. in addit...
