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.

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]

The c.1184T>G (p.I395S) alteration is located in exon 10 (coding exon 9) of the DYX1C1 gene. This alteration results from a T to G substitution at nucleotide position 1184, causing the isoleucine (I) at amino acid position 395 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
