Gene Gene information from NCBI Gene database.
Entrez ID 1497
Gene name Cystinosin, lysosomal cystine transporter
Gene symbol CTNS
Synonyms (NCBI Gene)
CTNS-LSBPQLC4SLC66A4
Chromosome 17
Chromosome location 17p13.2
Summary 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
