Distal trisomy 10 is a rare chromosomal disorder that causes several physical defects and intellectual disability. Humans, like all sexually reproducing species, have somatic cells that are in diploid [2N] state, meaning that N represent the number of chromosomes, and 2 the number of their copies.
DiGeorge syndrome is caused by a heterozygous deletion of part of the long arm (q) of chromosome 22, region 1, band 1, sub-band 2 (22q11.2). Approximately 80-90% of patients have a deletion of 3 Mb and 8% have a deletion of 1.5Mb.
10q26 deletion is an extremely rare genetic syndrome caused by terminal deletion of the long arm of chromosome 10 at 10q26. It is usually a de novo mutation.
The structure of 1q21.1 is complex. The area has a size of approximately 6 Megabase (Mb) (from 141.5 Mb to 147.9 Mb). Within 1q21.1 there are two areas where a duplication or deletion can be found: the TAR-area for the TAR syndrome and the distal area for other anomalies.
22q13 deletion syndrome. Other names. Phelan–McDermid syndrome. Chromosome 22 mutations cause 22q13 syndrome. Specialty. Genetics. 22q13 deletion syndrome, known as Phelan–McDermid syndrome ( PMS ), is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22.
duplication 15 q. Chromosome 15q duplication is an extremely rare genetic disorder in which there is an excess copy of a segment of DNA found on the long ("q") arm of human chromosome 15. As a result, affected cells contain a total of 3 copies of the duplicated bases, instead of the usual 2 copies - one inherited from the mother and one from ...
Jacobsen syndrome is a rare chromosomal disorder resulting from deletion of genes from chromosome 11 that includes band 11q24.1. It is a congenital disorder. Since the deletion takes place on the q arm of chromosome 11, it is also called 11q terminal deletion disorder. [1]
Chromosome 10 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 10 spans about 134 million base pairs (the building material of DNA ) and represents between 4 and 4.5 percent of the total DNA in cells .
Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene .
17q12 microdeletion syndrome. 17q12 microdeletion syndrome, also known as 17q12 deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome.
