Chromosome 15 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 15 spans about 99.7 million base pairs (the building material of DNA) and represents between 3% and 3.5% of the total DNA in cells. Chromosome 15 is an acrocentric chromosome, with a very small short arm (the "p" arm ...

Chromosome 15. Angelman syndrome is caused by the lack of expression of a gene known as UBE3A during development. [14] This gene is located within a region of chromosome 15 known as 15q11-q13 and is part of the ubiquitin pathway.

Isodicentric 15, also called marker chromosome 15 syndrome, [2] idic(15), partial tetrasomy 15q, or inverted duplication 15 (inv dup 15), is a chromosome abnormality in which a child is born with extra genetic material from chromosome 15. People with idic(15) are typically born with 47 chromosomes in their body cells, instead of the normal 46.
About 74% of cases occur when part of the father's chromosome 15 is deleted. [2] In another 25% of cases, the affected person has two copies of the maternal chromosome 15 from the mother and lacks the paternal copy. [2] As parts of the chromosome from the mother are turned off through imprinting, they end up with no working copies of certain ...
