What is the function of each chromosome?

Chromosomes are located inside of the nucleus of cells. Each chromosome is one long single molecule of DNA. This DNA contains important genetic information. Chromosomes have a unique structure, which helps to keep the DNA tightly wrapped around the proteins called histones.

What is chromosome 12 deletion syndrome?

Chromosome 12q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 12. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved.

What condition occurs when part of chromosome 12 is duplicated?

Chromosome 12q duplication is a chromosome abnormality that occurs when there is an extra copy of genetic material on the long arm (q) of chromosome 12. The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved.

What does the 13th chromosome control?

Chromosome 13 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 13 spans about 114 million base pairs (the building material of DNA) and represents between 3.5 and 4% of the total DNA in cells.

What chromosome is autism found on?

What is Trisomy 12 called?

Chromosome 12, trisomy 12p, is an extremely rare chromosomal disorder in which a portion of the short arm of the 12th chromosome (12p) appears three times (trisomy) rather than twice in cells of the body.

What is the rarest chromosomal disorder?

Trisomy 17 mosaicism is one of the rarest trisomies in humans. It is often incorrectly called trisomy 17 (also referred to as full trisomy 17), which is when three copies of chromosome 17 are present in all cells of the body.

What is Noonan syndrome?

Noonan syndrome is a genetic disorder that prevents normal development in various parts of the body. A person can be affected by Noonan syndrome in a wide variety of ways. These include unusual facial characteristics, short stature, heart defects, other physical problems and possible developmental delays.

What happens if you are missing chromosome 13?

Chromosome 13, Partial Monosomy 13q is usually apparent at birth and may be characterized by low birth weight, malformations of the head and facial (craniofacial) area, abnormalities of the eyes, defects of the hands and/or feet, genital malformations in affected males, and/or additional physical abnormalities.
