This gene encodes a protein with two doublecortin peptide domains. This domain has been demonstrated to bind tubulin and enhance microtubule polymerization.[3]
Clinical significance
Mutations in this gene have been associated with reading disability (RD), also referred to as developmental dyslexia.[3][4] But this is controverse since a recent study proposed that there is a "low likelihood of a direct deletion effect on reading skills." [5]
Changes in the DCDC2 gene are frequently found among dyslexics. Altered alleles often occur among children with reading and writing difficulties. The gene appears to have a strong linkage with the processing of speech information when writing.[6][7][8]
