What is the official name of the DNAH5 gene?
The official name of this gene is “dynein, axonemal, heavy chain 5.”
DNAH5 is the gene's official symbol. The DNAH5 gene is also known by other names, listed below.
What is the normal function of the DNAH5 gene?
The DNAH5 gene provides instructions for making a protein that is part of a group (complex) of proteins called dynein. This complex functions within cell structures called cilia. Cilia are microscopic, finger-like projections that stick out from the surface of cells. Coordinated back and forth movement of cilia can move the cell or the fluid surrounding the cell. Dynein produces the force needed for cilia to move.
Within the core of cilia (the axoneme), dynein complexes are part of structures known as inner dynein arms (IDAs) or outer dynein arms (ODAs) depending on their location. Coordinated movement of the dynein arms causes the entire axoneme to bend back and forth. IDAs and ODAs have different combinations of protein components (subunits) that are classified by weight as heavy, intermediate, or light chains. The DNAH5 gene provides instructions for making heavy chain 5, which is found in ODAs. Other subunits are produced from different genes.
Does the DNAH5 gene share characteristics with other genes?
The DNAH5 gene belongs to a family of genes called DN (axonemal dyneins).
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.
How are changes in the DNAH5 gene related to health conditions?
- primary ciliary dyskinesia - caused by mutations in the DNAH5 gene
More than 80 mutations in the DNAH5 gene have been found to cause primary ciliary dyskinesia, which is a condition characterized by respiratory tract infections, abnormal organ placement, and an inability to have children (infertility). DNAH5 gene mutations result in an absent or abnormal heavy chain 5. Without a normal version of this subunit, the ODAs cannot form properly and may be shortened or absent. As a result, cilia cannot produce the force needed to bend back and forth. Defective cilia lead to the features of primary ciliary dyskinesia.
Where is the DNAH5 gene located?
Cytogenetic Location: 5p15.2
Molecular Location on chromosome 5: base pairs 13,690,327 to 14,011,758
The DNAH5 gene is located on the short (p) arm of chromosome 5 at position 15.2.
More precisely, the DNAH5 gene is located from base pair 13,690,327 to base pair 14,011,758 on chromosome 5.
