Balanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report
One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...
متن کاملChromosomal rearrangements and speciation.
Several authors have proposed that speciation frequently occurs when a population becomes fixed for one or more chromosomal rearrangements that reduce fitness when they are heterozygous. This hypothesis has little theoretical support because mutations that cause a large reduction in fitness can be fixed through drift only in small, inbred populations. Moreover, the effects of chromosomal rearra...

متن کاملMYC Rearrangement Involving a Novel Non-immunoglobulin Chromosomal Locus in Precursor B-cell Acute Lymphoblastic Leukemia
MYC rearrangement, a characteristic cytogenetic abnormality of Burkitt lymphoma and several subsets of other mature B-cell neoplasms, typically involves an immunoglobulin gene partner. Herein, we describe a case of precursor B-cell lymphoblastic leukemia harboring a MYC rearrangement with a novel non-immunoglobulin partner locus. The patient was a 4-yr-old Korean boy with ALL of the precursor B...
