Genes affected

CNPY1 (HGNC:27786): (canopy FGF signaling regulator 1) Cnpy1 is expressed in the midbrain-hindbrain (MHB) boundary in zebrafish, binds FGFR1 (MIM 136350), and plays a role in FGF signaling (Hirate and Okamoto, 2006 [PubMed 16488878]).[supplied by OMIM, Dec 2008]

ENSG00000283128 (HGNC:):
