What is the official name of the SLC52A2 gene?
The official name of this gene is “solute carrier family 52 (riboflavin transporter), member 2.”
SLC52A2 is the gene's official symbol. The SLC52A2 gene is also known by other names, listed below.

What is the normal function of the SLC52A2 gene?
The SLC52A2 gene provides instructions for making a riboflavin transporter protein called RFVT2 (formerly known as RFT3). This protein moves (transports) a vitamin called riboflavin (also called vitamin B2) across the cell membrane. The RFVT2 protein is found at especially high levels in cells of the brain and spinal cord and is important for absorbing riboflavin from the bloodstream into these tissues.
In the cells of the body, including those in the brain and spinal cord, riboflavin is the core component of molecules called flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These molecules function as coenzymes, which means they help enzymes carry out chemical reactions. FAD and FMN are involved in many different chemical reactions and are required for a variety of cellular processes. One important role of these coenzymes is in the production of energy for cells. FAD and FMN are also involved in the breakdown (metabolism) of carbohydrates, fats, and proteins.
Does the SLC52A2 gene share characteristics with other genes?
The SLC52A2 gene belongs to a family of genes called SLC (solute carriers).
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 SLC52A2 gene related to health conditions?
- riboflavin transporter deficiency neuronopathy - caused by mutations in the SLC52A2 gene
- At least 11 mutations in the SLC52A2 gene have been found to cause riboflavin transporter deficiency neuronopathy. This neurological condition encompasses two disorders that were previously considered to be separate: Brown-Vialetto-Van Laere syndrome and Fazio-Londe disease. Some of the gene mutations involved in riboflavin transporter deficiency neuronopathy prevent production of the RFVT2 protein. Others lead to production of an abnormal protein with impaired ability to transport riboflavin. It is unclear how these changes lead to the nerve problems that cause hearing loss, muscle weakness in the face and limbs, and breathing problems in people with the disorder.
Where is the SLC52A2 gene located?
