Entrez Gene Summary for CECR1 Gene

  • This gene encodes a member of a subfamily of the adenosine deaminase protein family. The encoded protein is one of two adenosine deaminases found in humans, which regulate levels of the signaling molecule, adenosine. The encoded protein is secreted from monocytes undergoing differentiation and may regulate cell proliferation and differentiation. This gene may be responsible for some of the phenotypic features associated with cat eye syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

GeneCards Summary for CECR1 Gene

CECR1 (Cat Eye Syndrome Chromosome Region, Candidate 1) is a Protein Coding gene. Diseases associated with CECR1 include polyarteritis nodosa, childhood-onset and sneddon syndrome. GO annotations related to this gene include protein homodimerization activity and heparin binding.

UniProtKB/Swiss-Prot for CECR1 Gene

  • Adenosine deaminase that may contribute to the degradation of extracellular adenosine, a signaling molecule that controls a variety of cellular responses. Requires elevated adenosine levels for optimal enzyme activity. Binds to cell surfaces via proteoglycans and may play a role in the regulation of cell proliferation and differentiation, independently of its enzyme activity.

    • Homodimer. Interacts with adenosine receptors. Binds heparin.
    • Candidate gene for the Cat Eye Syndrome (CES), a developmental disorder associated with the duplication of a 2 Mb region of 22q11.2. Duplication usually takes in the form of a surpernumerary bisatellited isodicentric chromosome, resulting in four copies of the region (represents an inv dup(22)(q11)). CES is characterized clinically by the combination of coloboma of the iris and anal atresia with fistula, downslanting palpebral fissures, preauricular tags and/or pits, frequent occurrence of heart and renal malformations, and normal or near-normal mental development

Disorders for CECR1 Gene

(1) OMIM Diseases for CECR1 Gene (607575)


  • Polyarteritis nodosa (PAN) [MIM:615688]: A systemic necrotizing vasculitis that affects medium and small arteries. The ensuing tissue ischemia can affect any organ, including the skin, musculoskeletal system, kidneys, gastrointestinal tract, and the cardiovascular and nervous systems. Organ involvement and disease severity are highly variable. Clinical features include recurrent ischemic stroke affecting the small vessels of the brain and resulting in neurologic dysfunction, recurrent fever, myalgias, livedoid rash, gastrointestinal pain and hepatosplenomegaly. {ECO:0000269 PubMed:24552284, ECO:0000269 PubMed:24552285}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Sneddon syndrome (SNDDS) [MIM:182410]: A systemic non-inflammatory thrombotic vasculopathy characterized by the association of livedo racemosa, and in some cases livedo reticularis, with cerebrovascular disease. Livedo racemosa is a persistent net-like violaceous-cyanotic, mottled discoloration of the skin affecting the legs, the arms, the buttocks and the trunk; livedo reticularis is limited to the extremities and is visible only in the cold. Cerebrovascular features include recurrent transient ischemic attacks, infarcts, and rarely spinal strokes or intracranial or subarachnoid hemorrhages. Headache and vertigo may precede the onset of livedo racemosa and cerebrovascular manifestations by several years. Rare neurologic symptoms include seizures, chorea, or myelopathies. {ECO:0000269 PubMed:25075847}. Note=The disease is caused by mutations affecting the gene represented in this entry.
