SLC2A4RG

Chr 20

SLC2A4 regulator

Also known as: GEF, GLUT4EF, HDBP-1, HDBP1, Si-1-2, Si-1-2-19

SLC2A4RG encodes a nuclear transcription factor that activates transcription of the SLC2A4 gene (encoding GLUT4 glucose transporter) and other targets by binding to specific DNA sequences and interacting with myocyte enhancer factor 2. Mutations cause autosomal recessive intellectual disability with seizures, hypotonia, and distinctive facial features, typically presenting in early childhood. The gene shows moderate constraint against loss-of-function variants, suggesting some tolerance to haploinsufficiency.
