Cytogenetic Analysis of Lilium rosthornii

Cytogenetic analysis of 1284 cases of Down syndrome

Among 17786 karyotyres performed in our center,during 18 years (1357-1375),1300(7.3%) cases of chromosome 21 aberration,including 1284(98.77%) of Down syndrome have been detected.1191 of cases (92.76%) born free trisomy 21:61 cases (4.75%) revealed translocation and 32 cases (2.4%) showed mosaic pattern.among the pateints,59 had robertsonian translocation,2 had translocation between chromosome ...

Cytogenetic analysis of meningiomas.

Cytogenetic analysis of 4 cases of meningiomas from 3 male and 1 female patients is reported. One of male patients suffered from neurofibromatosis type 2. Histologically, the meningiomas were meningotheliomatous (1), transitional (2), and psammomatous (1). Chromosomal abnormalities were found in all cases with a karyotype 45,XY,-22, 45,XY,-16, 45,XX,-2, and 45,XY,t (15p;22q), respectively. Mono...

Cytogenetic Analysis of Spontaneous Miscarriage

Correlative Interphase Cytogenetic Analysis

Background: A patient with multiple myeloma developed myelodysplastic syndrome (MDS). Chromosomal analysis performed after the development of MDS revealed monosomy of chromosome 9 in all the meta-phases. We wished to identify the extent of the clone with the chromosomal abnormality originating from MDS clone. Methods: A correlative interphase study by fluorescence in situ hybridization (FISH) w...

[Cytogenetic analysis of choroidal melanoma].

PURPOSE To investigate the presence of known cytogenetic alterations of choroidal melanoma in a series of patients diagnosed and treated in our Ocular Oncology Service. A review of the present literature on this topic is also presented. METHODS Microsatellite analysis (MSA) studies on loss of heterozygosity (LOH) of chromosome 3, as well as multiplex ligation prove amplification (MLPA) on chr...
