Genes affected

HYCC1 (HGNC:24587): (hyccin PI4KA lipid kinase complex subunit 1) The protein encoded by this gene may play a part in the beta-catenin/Lef signaling pathway. Expression of this gene is down-regulated by beta-catenin. Defects in this gene are a cause of hypomyelination with congenital cataract (HCC). [provided by RefSeq, Oct 2008]
