Solute carrier family 13 (sodium-dependent citrate transporter), member 5 also known as theNa+/citrate cotransporter ormIndy is aprotein that in humans is encoded by the SLC13A5gene.[5] It is the mammalian homolog of the flyIndy gene.
In 2014, by means ofexome sequencing it was determined that a genetic mutation of the gene is the cause of a rareSLC13A5 Epilepsy.[6] Mutations in SLC13A5 causeautosomal recessive epileptic encephalopathy with seizure onset in the first days of life.[6] Those afflicted suffer from seizures, global developmental delay, movement disorder and hypotonia.
Reduced expression of homologous genes is associated with longer lifespan inDrosophila melanogaster andCaenorhabditis elegans,[7][8] and obesity protection inlaboratory mice.[9] Increased expression is associated with type 2 diabetes and non-alcoholic fatty liver disease. A sugary diet upregulates the expression of the gene, and so doesInterleukin 6 signaling.[10]
