Chromosome 10

Reviewed August 2007

What is chromosome 10?

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 10, one copy inherited from each parent, form one of the pairs. Chromosome 10 spans about 135 million DNA building blocks (base pairs) and represents between 4 percent and 4.5 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 10 likely contains between 800 and 1,200 genes.

Genes on chromosome 10 are among the estimated 20,000 to 25,000 total genes in the human genome.

Genetics Home Reference includes these genes on chromosome 10:

  • ACADSB:acyl-Coenzyme A dehydrogenase, short/branched chain
  • CDH23:cadherin-like 23
  • EGR2:early growth response 2 (Krox-20 homolog, Drosophila)
  • ERCC6:excision repair cross-complementing rodent repair deficiency, complementation group 6
  • FGFR2:fibroblast growth factor receptor 2 (bacteria-expressed kinase, keratinocyte growth factor receptor, craniofacial dysostosis 1, Crouzon syndrome, Pfeiffer syndrome, Jackson-Weiss syndrome)
  • LGI1:leucine-rich, glioma inactivated 1
  • LIPA:lipase A, lysosomal acid, cholesterol esterase (Wolman disease)
  • MAT1A:methionine adenosyltransferase I, alpha
  • PAX2:paired box 2
  • PCBD1:pterin-4 alpha-carbinolamine dehydratase/dimerization cofactor of hepatocyte nuclear factor 1 alpha
  • PCDH15:protocadherin 15
  • PSAP:prosaposin (variant Gaucher disease and variant metachromatic leukodystrophy)
  • PTEN:phosphatase and tensin homolog (mutated in multiple advanced cancers 1)
  • RET:ret proto-oncogene
  • SMC3:structural maintenance of chromosomes 3
  • UROS:uroporphyrinogen III synthase (congenital erythropoietic porphyria)

What chromosomal conditions are related to chromosome 10?

The following conditions are caused by changes in the structure or number of copies of chromosome 10.

cancers

Changes in the number and structure of chromosome 10 are associated with several types of cancer. For example, a loss of all or part of chromosome 10 is often found in brain tumors called gliomas, particularly in aggressive, fast-growing gliomas. The association of cancerous tumors with a loss of chromosome 10 suggests that some genes on this chromosome play critical roles in controlling the growth and division of cells. Without these genes, cells could grow and divide too quickly or in an uncontrolled way, resulting in cancer. Researchers are working to identify the specific genes on chromosome 10 that may be involved in the development and progression of gliomas.

A complex rearrangement (translocation) of genetic material between chromosomes 10 and 11 is associated with several types of blood cancer known as leukemias. This chromosomal abnormality is found only in cancer cells. It fuses part of a specific gene from chromosome 11 (the MLL gene) with part of another gene from chromosome 10 (the MLLT10 gene). The abnormal protein produced from this fused gene signals cells to divide without control or order, leading to the development of cancer.

Crohn disease

Variations in a particular region of chromosome 10 have been associated with the risk of developing Crohn disease. These genetic changes are located on the long (q) arm of the chromosome at a position designated 10q21.1. Researchers refer to this part of chromosome 10 as a "gene desert" because it contains no known genes. However, it may contain stretches of DNA that help regulate nearby genes such as ERG2. This gene has a potential role in immune system function, and researchers are interested in studying the gene further to determine whether it is associated with Crohn disease risk.

other chromosomal conditions

Other changes in the number or structure of chromosome 10 can have a variety of effects. Intellectual disability, delayed growth and development, distinctive facial features, and heart defects are common features. Changes to chromosome 10 include an extra piece of the chromosome in each cell (partial trisomy), a missing segment of the chromosome in each cell (partial monosomy), and an abnormal structure called a ring chromosome 10. Ring chromosomes occur when a chromosome breaks in two places and the ends of the chromosome arms fuse together to form a circular structure. Rearrangements (translocations) of genetic material between chromosomes can also lead to extra or missing material from chromosome 10.

Is there a standard way to diagram chromosome 10?

Geneticists use diagrams called ideograms as a standard representation for chromosomes. Ideograms show a chromosome's relative size and its banding pattern. A banding pattern is the characteristic pattern of dark and light bands that appears when a chromosome is stained with a chemical solution and then viewed under a microscope. These bands are used to describe the location of genes on each chromosome.
