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.[1] In melanocytic cells this gene is regulated by the Microphthalmia-associated transcription factor.[2][3]

Clinical significance[edit]

Mutations in the CLCN7 gene have been reported to be associated with autosomal dominant osteopetrosis type II, a rare disease of bones.[4]
