Genes affected
DNAAF4 (HGNC:21493): (dynein axonemal assembly factor 4) This gene encodes a tetratricopeptide repeat domain-containing protein. The encoded protein interacts with estrogen receptors and the heat shock proteins, Hsp70 and Hsp90. An homologous protein in rat has been shown to function in neuronal migration in the developing neocortex. A chromosomal translocation involving this gene is associated with a susceptibility to developmental dyslexia. Mutations in this gene are associated with deficits in reading and spelling. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream cell cycle progression 1 (CCPG1) gene. [provided by RefSeq, Mar 2011]
DNAAF4-CCPG1 (HGNC:43019): (DNAAF4-CCPG1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring dyslexia susceptibility 1 candidate 1 (DYX1C1) and cell cycle progression 1 (CCPG1) genes on chromosome 15. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Mar 2011]
