| Background One important language gene is , a mutation of which affects language and speech in relatively rare and severe forms. However, certain genetic markers adjacent to gene are highly suspected to be involved in common forms of specific language impairment (SLI). Identification of these genetic loci related to SLI may yield new insights into its causes, along with improved diagnosis, and treatment. Aim of the work To study the association of SLI to two genetic markers residing near gene, namely, the repeat unit GATA of D7S3052 marker and GATT tetranucleotide repeats in intron 6 of gene. Patients and methods The current study included 50 children with SLI and 50 normal controls, aged 3–8 years. All participants were subjected to genetic molecular association study as well as detailed protocol of assessment including full history and examination, and evaluation of language skills and mental ability (intelligence quotient). Results There was no difference between the SLI and normal groups regarding molecular results of GATT repeats of gene, and there was a nonsignificant difference regarding results of GATA repeats of D7S3052 marker ( > 0.05). Conclusion The association of SLI with D7S3052 marker near gene in current study is statistically nonsignificant. However, a statistical significance of this association could be expected with a larger number of cases, more diversity of SLI types and degrees, and more comprehensive procedures. | ||||
