The present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of Anchusa subgenus Buglossum Gusul. from Iran. All populationsshowed the chromosome number 2n= 4x= 32. It is the first meiotic study for A. subg.Buglossum. We discuss some habit form and evolutionary aspect in the light of cytogeneticdata. The origin of polyploidy (auto-allopolyploidy)...
Interstitial deletions of 4q are rarely reported, vary in size, and have limited genotype-phenotype correlations. Here, genome-wide array CGH analysis identified a 21.6 Mb region of copy number loss at 4q12-q21.1 in a patient diagnosed with dysmorphism, linear skin pigmentation, and hepatomegaly. An additional small ring chromosome was detected in 5/30 cells examined via G-banding. Confirmation...
Recently, we and other groups reported in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) a strong correlation between cytogenetic rearrangements leading to 17p deletion, a typical form of dysgranulopoiesis combining pseudo-Pelger-Huët hypolobulation and small vacuoles in neutrophils, and p53 mutation. To gain further insight into this "17p-syndrome," we studied 17 cases of AML ...
OBJECTIVE Cardiovascular anomalies are present in 75% to 80% of patients with a chromosome 22q11 deletion. In the majority of cases, the cardiovascular defect becomes evident in the neonatal period and is often the initial manifestation of the chromosome 22q11 deletion syndrome. However, a 22q11 deletion may also be associated with cardiovascular defects that are less obvious, such as a vascula...
Ring chromosomes are rare entities, usually associated with phenotypic abnormalities in correlation with the loss of genetic material. There are various breakpoints and sometimes there is a dynamic mosaicism that is reflected in clinical features. Most of the ring chromosomes are de novo occurrences. Our study reflects the experience of three Romanian cytogenetic laboratories in the field of ri...
In this study we tried to define incidence and types of chromosomal aberrations (CAs) caused by radiotherapy (RT) in circulating lymphocytes from patients with lung cancer. For this purpose, we used cumulative dose-effect relationship, and correlate these data with statistical parameters. CAs were evaluated in terms of chromosome break, dicentric, ring and chromosome gap. Abnormal metaphase num...
