CTNS may also refer to the Center for Theology and the Natural Sciences.

CTNS is the gene that encodes the protein cystinosin in humans. Cystinosin is a lysosomal seven-transmembrane protein that functions as an active transporter for the export of cystine molecules out of the lysosome.

Mutations in CTNS are responsible for cystinosis, an autosomal recessive lysosomal storage disease.
