CTNS Chromosome 17
Cystinosin, lysosomal cystine transporter
Upload your DNA to see your personal genotypes for variants in CTNS.
What This Gene Does
This gene encodes a seven-transmembrane domain protein that functions to transport cystine out of lysosomes. Its activity is driven by the H+ electrochemical gradient of the lysosomal membrane. Mutations in this gene cause cystinosis, a lysosomal storage disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]
