The official name of this gene is “zinc finger, MYM-type 2.”
ZMYM2 is the gene's official symbol. The ZMYM2 gene is also known by other names, listed below.
The ZMYM2 gene (previously known as ZNF198) provides instructions for making a protein whose function is not clearly understood. It is a member of a family of zinc finger proteins, which contain one or more short regions called zinc finger domains. The zinc finger domains in the ZMYM2 protein are thought to allow it to regulate interactions between other proteins. ZMYM2 is found in the nucleus of the cell, where it likely associates with other proteins. Through these associations, the ZMYM2 protein may be involved in repairing DNA mistakes, controlling gene activity, or forming structures in the nucleus called PML nuclear bodies that block the growth and division of cells and promote their self-destruction (apoptosis).
The ZMYM2 gene belongs to a family of genes called ZMYM (zinc fingers, MYM type).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? (http://ghr.nlm.nih.gov/handbook/howgeneswork/genefamilies) in the Handbook.
A genetic change involving the ZMYM2 gene causes most cases of 8p11 myeloproliferative syndrome. This condition is characterized by an increased number of white blood cells (myeloproliferative disorder) and the development of lymphoma, a blood-related cancer that causes tumor formation in the lymph nodes. The myeloproliferative disorder usually develops into another form of blood cancer called acute myeloid leukemia. 8p11 myeloproliferative syndrome most commonly results from a rearrangement (translocation) of genetic material between chromosome 13 and chromosome 8. This genetic change fuses part of the ZMYM2 gene on chromosome 13 with part of the FGFR1 gene on chromosome 8. The translocation is found only in cancer cells.
The protein produced from the normal FGFR1 gene can turn on cellular signaling that helps the cell respond to its environment, for example by stimulating cell growth. The protein produced from the fused ZMYM2-FGFR1 gene leads to constant FGFR1 signaling. The uncontrolled signaling promotes continuous cell growth and division, leading to cancer.
Cytogenetic Location: 13q11-q12
Molecular Location on chromosome 13: base pairs 19,957,567 to 20,091,828
The ZMYM2 gene is located on the long (q) arm of chromosome 13 between positions 11 and 12.
More precisely, the ZMYM2 gene is located from base pair 19,957,567 to base pair 20,091,828 on chromosome 13.
