What is the official name of the CERKL gene?

The official name of this gene is “ceramide kinase like.”

CERKL is the gene's official symbol. The CERKL gene is also known by other names, listed below.

What is the normal function of the CERKL gene?

From NCBI Gene (

This gene was initially identified as a locus (RP26) associated with an autosomal recessive form of retinitis pigmentosa (arRP) disease. This gene encodes a protein with ceramide kinase-like domains, however, the protein does not phosphorylate ceramide and its target substrate is currently unknown. This protein may be a negative regulator of apoptosis in photoreceptor cells. Mutations in this gene cause a form of retinitis pigmentosa characterized by autosomal recessive cone and rod dystrophy (arCRD). Alternative splicing of this gene results in multiple transcript variants encoding different isoforms and non-coding transcripts.[provided by RefSeq, May 2010]

From UniProt (CERKL_HUMAN) (

Has no detectable ceramide-kinase activity. Overexpression of CERKL protects cells from apoptosis in oxidative stress conditions.

How are changes in the CERKL gene related to health conditions?

Genetics Home Reference provides information about retinitis pigmentosa, which is associated with changes in the CERKL gene.
UniProt (CERKL_HUMAN) ( provides the following information about the CERKL gene's known or predicted involvement in human disease.

Retinitis pigmentosa 26 (RP26): A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. The disease is caused by mutations affecting the gene represented in this entry.

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the CERKL gene.
