Genes affected

CRLF1 (HGNC:2364): (cytokine receptor like factor 1) This gene encodes a member of the cytokine type I receptor family. The protein forms a secreted complex with cardiotrophin-like cytokine factor 1 and acts on cells expressing ciliary neurotrophic factor receptors. The complex can promote survival of neuronal cells. Mutations in this gene result in Crisponi syndrome and cold-induced sweating syndrome. [provided by RefSeq, Oct 2009]

CRLF1 Gene-Disease associations (from GenCC):

• Cold-induced sweating syndrome 1
