Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

Robertsonian translocation is the most common form of chromosomal translocation in humans. It means that two chromosomes, the structures that make up a person’s DNA, join together in an abnormal way.

A genetics research team based at The Children's Hospital of Philadelphia continues to discover recurrent translocations—places in which two chromosomes exchange pieces of themselves. As many as 1 in ...

STRUCTURAL heterozygosis is the existence in heterozygous state of an interchromosomal or intrachromosomal rearrangement. Fragmentation of two chromosomes and the mutual exchange through reunion of ...

Translocations are chromosomal "cut and paste" errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but ...

MONGOLISM is usually the result of trisomy of a small acrocentric chromosome in Group 21–22 in the Denver Classification. This is generally referred to as 21-trisomy. These patients have a somatic ...

Translocations are chromosomal “cut and paste” errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but ...

As the human genome gradually yields up its secrets, scientists are finding some genetic events, such as rearrangements in chromosomes, are less random than they had previously thought. Originating as ...

Changes in either chromosome structure or number can occur during cell division. Each human has 46 chromosomes, 22 pairs of autosomes and 1 pair of sex chromosomes (XX: female or XY: male). During ...

Abnormalities in the structure of chromosomes within someone’s genetic makeup are called structural chromosomal abnormalities. Robertsonian translocations are very rare structural chromosomal ...
