What is the official name of the DYNC1H1 gene?
The official name of this gene is “dynein, cytoplasmic 1, heavy chain 1.”
DYNC1H1 is the gene's official symbol. The DYNC1H1 gene is also known by other names, listed below.

What is the normal function of the DYNC1H1 gene?
The DYNC1H1 gene provides instructions for making a protein that is part of a group (complex) of proteins called dynein. This complex is found in the fluid inside cells (cytoplasm). Dynein is turned on (activated) by attaching (binding) to another complex called dynactin. This dynein-dynactin complex binds to various materials within cells. Using energy provided by molecules called ATP, the dynein-dynactin complex moves material along a track-like system of small tubes called microtubules, similar to a conveyer belt. The dynein-dynactin complex is necessary for protein transport, positioning of cell compartments, mobility of structures within the cell, and many other cell processes. In nerve cells (neurons), dynein helps neighboring cells communicate by transporting sac-like structures called synaptic vesicles that contain chemical messengers. When synaptic vesicles are passed from one neuron to another, the dynein-dynactin complex transports the vesicle from the edge of the cell to the center where the chemical message is received.
The parts (subunits) of a dynein complex are classified by weight as heavy, intermediate, light intermediate, or light chains. Two heavy chain proteins bind together to form the core of the dynein complex. Combinations of intermediate, light intermediate, and light chains make up the rest of the complex. The protein produced from the DYNC1H1 gene is a heavy chain. Other subunits are produced from different genes.
Does the DYNC1H1 gene share characteristics with other genes?
The DYNC1H1 gene belongs to a family of genes called DYN (cytoplasmic 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? in the Handbook.
How are changes in the DYNC1H1 gene related to health conditions?
Genetics Home Reference provides information about Charcot-Marie-Tooth disease, which is also associated with changes in the DYNC1H1 gene.
Where is the DYNC1H1 gene located?
Cytogenetic Location: 14q32
