Also known as FHF1
Summary
FGF12 (fibroblast growth factor 12, HGNC:3668) is a protein-coding gene on chromosome 3q28-q29, encoding Fibroblast growth factor 12 (P61328). Involved in nervous system development and function.
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, and invasion. This growth factor lacks the N-terminal signal sequence present in most of the FGF family members, but it contains clusters of basic residues that have been demonstrated to act as a nuclear localization signal. When transfected into mammalian cells, this protein accumulated in the nucleus, but was not secreted. The specific function of this gene has not yet been determined.

Function. Involved in nervous system development and function. Involved in the positive regulation of voltage-gated sodium channel activity. Promotes neuronal excitability by elevating the voltage dependence of neuronal sodium channel SCN8A fast inactivation.
Subunit / interactions. Interacts with the C-terminal region of SCN9A.
Subcellular location. Nucleus.
Tissue specificity. Brain, eye and testis; highly expressed in embryonic retina, olfactory epithelium, olfactory bulb, and in a segmental pattern of the body wall; in adult olfactory bulb, less in cerebellum, deep cerebellar nuclei, cortex and multiple midbrain structures.
Disease relevance. Developmental and epileptic encephalopathy 47 (DEE47) [MIM:617166] A form of epileptic encephalopathy, a heterogeneous group of severe early-onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the heparin-binding growth factors family.
