What is the official name of the SH3TC2 gene?

The official name of this gene is “SH3 domain and tetratricopeptide repeats 2.”

SH3TC2 is the gene's official symbol. The SH3TC2 gene is also known by other names, listed below.

What is the normal function of the SH3TC2 gene?

The SH3TC2 gene is active in the nervous system and provides instructions for making a protein whose function is unknown. Based on its structure, the SH3TC2 protein probably interacts with other proteins and may assist in assembling proteins into a group or complex.

Does the SH3TC2 gene share characteristics with other genes?

The SH3TC2 gene belongs to a family of genes called TTC (tetratricopeptide (TTC) repeat domain containing).

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 SH3TC2 gene related to health conditions?

Charcot-Marie-Tooth disease - caused by mutations in the SH3TC2 gene

Researchers have identified at least 19 SH3TC2 gene mutations that cause a form of Charcot-Marie-Tooth disease known as type 4C. Charcot-Marie-Tooth disease is a group of progressive disorders that affect the peripheral nerves. Peripheral nerves connect the brain and spinal cord to muscles and to sensory cells that detect sensations such as touch, pain, heat, and sound.

Most of the SH3TC2 gene mutations that cause Charcot-Marie-Tooth disease disrupt production of the SH3TC2 protein, resulting in an abnormally short or unstable version of this protein. Some mutations change one of the building blocks (amino acids) used to make the SH3TC2 protein, which alters the protein's structure. It is unclear how SH3TC2 gene mutations cause the signs and symptoms of type 4C Charcot-Marie-Tooth disease.

Where is the SH3TC2 gene located?

Cytogenetic Location: 5q32

Molecular Location on chromosome 5: base pairs 148,982,149 to 149,063,173

The SH3TC2 gene is located on the long (q) arm of chromosome 5 at position 32.

The SH3TC2 gene is located on the long (q) arm of chromosome 5 at position 32.

More precisely, the SH3TC2 gene is located from base pair 148,982,149 to base pair 149,063,173 on chromosome 5.
