Fibroblast growth factor 13 is a protein that in humans is encoded by the FGF13 gene.^[5][6]

The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth, invasion, and neuronal physiology. This gene is located to a region associated with Börjeson-Forssman-Lehmann syndrome (BFLS), a syndromal X-linked intellectual disability, which suggests it may be a candidate gene for familial cases of the BFL syndrome. The function of this gene has not yet been determined. Several alternatively spliced transcripts encoding different isoforms have been described for this gene.^[6] FGF13 isoform 1 (FGF13A) binds to the leucine-rich repeats of the hominid-specific receptor LRRC37B.^[7] In human pyramidal neurons of the cerebral cortex, this interaction leads to a lower excitability,^[7] a divergent cellular property of human pyramidal neurons compared to other mammals.^[7]
