## TL;DR

FGF13 (Fibroblast growth factor 13) is a gene. The public catalogues list it as a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Prostate cancer.

## Summary

Microtubule-binding protein which directly binds tubulin and is involved in both polymerisation and stabilisation of microtubules. Through its action on microtubules, may participate in the refinement of axons by negatively regulating axonal and leading processes branching. Plays a crucial role in neuron polarisation and migration in the cerebral cortex and the hippocampus.

CIViC holds 1 clinical evidence item and 0 assertions across 1 variant.

- Biology: Microtubule-binding protein which directly binds tubulin and is involved in both polymerisation and stabilisation of microtubules. Through its action on microtubules, may participate in the refinement of axons by negatively regulating axonal and leading processes branching. Plays a crucial role in neuron polarisation and migration in the cerebral cortex and the hippocampus. Regulates voltage-gated sodium channel transport and function. May also play a role in MAPK signalling. Required for the development of axonal initial segment-targeting inhibitory GABAergic synapses made by chandelier neurons. Location: Nucleus; Cytoplasm; Cell projection, filopodium; Cell projection, growth cone (UniProt). Locus Xq26.3-q27.1 (HGNC).

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: CIViC holds 1 clinical evidence items on its variants. Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
