Genes affected

TACSTD2 (HGNC:11530): (tumor associated calcium signal transducer 2) This intronless gene encodes a carcinoma-associated antigen. This antigen is a cell surface receptor that transduces calcium signals. Mutations of this gene have been associated with gelatinous drop-like corneal dystrophy.[provided by RefSeq, Dec 2009]

TACSTD2 Gene-Disease associations (from GenCC):

• gelatinous drop-like corneal dystrophy
