Chloride channel 7 alpha subunit also known as H⁺/Cl⁻ exchange transporter 7 is a protein that in humans is encoded by the CLCN7 gene. In melanocytic cells this gene is regulated by the Microphthalmia-associated transcription factor.

Clinical significance

Mutations in the CLCN7 gene have been reported to be associated with autosomal dominant osteopetrosis type II, a rare disease of bones.
