Cytokine receptor-like factor 1 is a protein that in humans is encoded by the CRLF1 gene.[1][2]

Function

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.[2]

Clinical significance

Mutations in this gene are associated with two conditions, both rare:

It is unknown whether the two conditions are distinct clinical entities or a single clinical entity with variable expressions.[3] Other characteristic features in CRLF1 mutation include marfanoid habitus with progressive kyphoscoliosis and craniofacial characteristics including dolichocephaly, a slender face with poor expression, a nose with hypoplastic nares, malar hypoplasia and prognathism.[3]
