How genes may affect dyslexia

Writing in the Journal of the Federation of American Societies for Experimental Biology under the title “The Complex of TFII-I, PARP1, and SFPQ Proteins Regulates the DYX1C1 Gene Implicated in Neuronal Migration and Dyslexia,” Isabel Tapia-Páez and colleagues revealed that they have discovered a group of proteins that apparently act together to control the transcription of DNA (deoxyribonucleic acid that forms genetic material) code into RNA (ribonucleic acid which controls synthesis of proteins) code. Although the gene DYX1C1 has been implicated in only a small proportion of cases of dyslexia, it is important in general because the finding moves researchers closer to understanding how genes can influence behavior as complex as reading.
