Summary
DCDC2 (doublecortin domain containing 2, HGNC:18141) is a protein-coding gene on chromosome 6p22.3, encoding Doublecortin domain-containing protein 2 (Q9UHG0). Protein that plays a role in the inhibition of canonical Wnt signaling pathway.
This gene encodes a doublecortin domain-containing family member. The doublecortin domain has been demonstrated to bind tubulin and enhance microtubule polymerization. This family member is thought to function in neuronal migration where it may affect the signaling of primary cilia. Mutations in this gene have been associated with reading disability (RD) type 2, also referred to as developmental dyslexia. Alternatively spliced transcript variants encoding the same protein have been found for this gene.

Subcellular location. Cell projection. Cilium. Cytoplasm. Cytoskeleton. Cilium axoneme. Kinocilium.
Tissue specificity. Ubiquitously expressed. In brain, highly expressed in the entorhinal cortex, inferior temporal cortex, medial temporal cortex, hypothalamus, amygdala and hippocampus. Expressed in liver by cholangiocytes, the epithelial cells of the bile ducts (at protein level).
Disease relevance. Dyslexia 2 (DYX2) [MIM:600202] A relatively common, complex cognitive disorder characterized by an impairment of reading performance despite adequate motivational, educational and intellectual opportunities. It is a multifactorial trait, with evidence for familial clustering and heritability. Disease susceptibility is associated with variants affecting the gene represented in this entry. Nephronophthisis 19 (NPHP19) [MIM:616217] A form of nephronophthisis, an autosomal recessive disorder characterized by chronic tubulointerstitial nephritis resulting in end-stage renal disease. NPHP19 patients also manifest hepatosplenomegaly, hepatic fibrosis, destruction of the bile ducts, focal bile ductal proliferation, ductal plate malformation, and cholestasis. The disease is caused by variants affecting the gene represented in this entry. Deafness, autosomal recessive, 66 (DFNB66) [MIM:610212] A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. The disease is caused by variants affecting the gene represented in this entry. Sclerosing cholangitis, neonatal (NSC) [MIM:617394] An autosomal recessive form of liver disease with onset in infancy. Affected infants have jaundice, cholestasis, acholic stools, and progressive liver dysfunction resulting in fibrosis and cirrhosis. Cholangiography shows patent biliary ducts, but there are bile duct irregularities. The disease is caused by variants affecting the gene represented in this entry.
