27 Abnormal Organ and Cellular Growth with Various Chromosomal Disorders

Abnormal ("ringed") sideroblasts in various hematologic and non-hematologic disorders.

Organ site specificity for cancer in chromosomal instability disorders.

DNA rearrangement rather than point mutation is an emerging hypothesis for human carcinogenesis. Although there is no direct evidence for this hypothesis, indirect evidence is provided by cancer cytogenetics and genetics. It has been suggested that patients with Bloom's syndrome, a disorder of spontaneous chromosomal rearrangement, develop the common fatal internal cancers and thus that genetic...

Toxoplasmosis and its Relationship with Various Mental Disorders

Toxoplasmosis is a globally distributed disease caused by a parasitic protozoan called Toxoplasma gondii (T. gondii) in humans and animals that often develops asymptomatic acquired infections but the important aspect of this parasitic infection is the possible risk of congenital transmission and its severe effects on the fetus such as hydrocephalus, microcephaly, deafness and abortion up to mil...

Chromosomal disorders associated with epilepsy.

Epilepsy is among the most common findings associated with chromosome aberrations, particularly those involving autosomal chromosome imbalances. Most chromosome aberrations can be associated with different seizure types, but there are a few aberrations featuring specific seizure and electroencephalographic (EEG) patterns. The analysis of electro-clinical patterns associated with chromosomal abe...

Chromosomal Abnormalities in Regions 8q22 and 13q32 Associated with Different Disorders in an Iranian Family

Chromosomal abnormalities are major causes of infertility, miscarriage and birth of handicapped progeny. In human live births, the prevalence of a chromosome aberration is ?0.5% and, of these, 0.1–0.3% correspond to structural chromosome rearrangements such as translocations, inversions, insertions and deletions .Our proband is an infant who had died 4 hours after birth due to a variety of abno...
