Protein

H(+)/Cl(-) exchange transporter 4

Gene

CLCN4

Organism

Homo sapiens (Human)

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Proton-coupled chloride transporter. Functions as antiport system and exchanges chloride ions against protons.2 Publications

Miscellaneous

The CLC channel family contains both chloride channels and proton-coupled anion transporters that exchange chloride or another anion for protons. The presence of conserved gating glutamate residues is typical for family members that function as antiporters.

Pathology & Biotechⁱ

Involvement in diseaseⁱ

Mental retardation, X-linked 49 (MRX49)2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations.
