LCHN is a protein that in humans is encoded by the KIAA1147 gene (NCBI Gene ID 57189) located on chromosome 7. It is likely part of the tripartite DENN domain family of proteins that often function as Rab-GEFs to regulate vesicular trafficking. Both the mRNA and protein have been shown to be upregulated following ischemic stroke, and to be produced at altered levels in patients with FTD-ALS, however the gene's contribution to these states is not well understood.
