The concurrence of congenital trisomy 8 mosaicism and gestational trophoblastic disease in a forty-two-year-old Gravida IV, Para IV female has been described. In contrast to other cases in the literature, this patient had no additional confounding chromosomal abnormalities other than trisomy 8. To the best of our knowledge, this was the only reported case of constitutional trisomy 8 mosaicism a...
INTRODUCTION Acute myeloid leukemia (AML) is a genetically heterogeneous disease at both the cytogenetic and molecular levels. In AML cells many chromosomal aberrations are observed, some of them being characteristic of a particular subtype of patients, and others being less significant. Besides chromosomal abnormalities, the leukemic cells can have a variety of mutations involving individual g...
Laryngeal squamous cell carcinoma (LSCC) is a common cancer of the upper respiratory tract. The cytogenetic and molecular events involved in the pathogenesis of LSCC are not well understood. In this study, a combined strategy of conventional cytogenetics, fluorescent in situ hybridization (FISH) and microsatellite polymerase chain reaction was performed to analyze the deletion of chromosome 6 i...
BACKGROUND Several attempts have been made to determine whether interphase fluorescence in situ hybridization (I-FISH) on bone marrow or peripheral blood specimens is a good alternative to conventional cytogenetics (CC) in calculating the residual proportion of Philadelphia (Ph) chromosome-positive cells during treatment follow-up of patients with chronic myeloid leukemia. MATERIALS AND METHO...
BACKGROUND AND OBJECTIVES Conventional cytogenetic studies have revealed more number of females in spontaneous abortion and it has been assumed that a large proportion of those were resulted from maternal contamination and overgrowth of maternal decidua in long term culture. In this study we have attempted to overcome difficulties of conventional cytogenetics by using meticulous tissue dissecti...
