[1] The language phenotype of a small geographically isolated russian-speaking population: Implications for genetic and clinical studies of developmental language disorder / N. Rakhlin, S. A. Kornilov, D. Palejev et al. // Applied Psycholinguistics. — 2013. — Vol. 34, no. 5. — P. 971–1003. This article describes the results of an epidemiological study of developmental language disorder (DLD) in an isolated rural Russian population. We report an atypically high prevalence of DLD across all age groups when contrasted with a comparison population. The results are corroborated by a set of comparisons of school-aged children from the target population with their age peers and mean length of utterance matches from the comparison population. We also investigate the relationship between nonverbal cognition, verbal working memory, and expressive language performance in the population, and find statistically significant but small effect sizes. Finally, we describe the complex and heterogeneous structure of the phenotype in the population along with patterns of its vertical transmission on the basis of the exemplar pedigrees, and discuss the implications of our findings for genetic and clinical studies of DLD.
