Association of the DYX1C1 Dyslexia Susceptibility Gene with Orthography in the Chinese Population

Abstract

Plusieurs études indépendantes ont soutenu l'association de DYX1C1 avec la dyslexie, mais son rôle dans le développement général de la lecture reste incertain. Ici, nous avons étudié la contribution de ce gène à la lecture, en mettant l'accent sur les compétences orthographiques, dans un échantillon de 284 enfants chinois non apparentés âgés de 5 à 11 ans qui participaient à l'étude longitudinale chinoise du développement de la lecture. Nous avons testé cette association en utilisant une approche quantitative pour la lecture des caractères chinois, la dictée des caractères chinois, le jugement orthographique et les compétences visuelles. Des associations significatives ou marginalement significatives ont été observées au marqueur rs11629841 avec les jugements orthographiques des enfants à 7 et 8 ans (toutes les valeurs de P <0,020). Des associations significatives avec la dictée des caractères chinois (toutes les valeurs de P <0,013) ont également été observées pour ce polymorphisme mononucléotidique (SNP) à l'âge de 9, 10 et 11 ans. D'autres analyses ont révélé que l'association avec les compétences orthographiques était spécifique au traitement de composantes spécifiques des caractères (valeurs P <0,046). Aucune association n'a été trouvée au SNP de rs3743205 ou rs57809907. Nos résultats suggèrent que DYX1C1 influence le développement de la lecture dans la population chinoise générale et soutient un effet universel de ce gène.

Varios estudios independientes han apoyado la asociación de DYX1C1 con la dislexia, pero su papel en el desarrollo general de la lectura sigue sin estar claro. Aquí, investigamos la contribución de este gen a la lectura, con un enfoque en las habilidades ortográficas, en una muestra de 284 niños chinos no relacionados de 5 a 11 años que participaban en el Estudio Longitudinal Chino del Desarrollo de la Lectura. Probamos esta asociación utilizando un enfoque cuantitativo para la lectura de caracteres chinos, el dictado de caracteres chinos, el juicio ortográfico y las habilidades visuales. Se observaron asociaciones significativas o marginalmente significativas en el marcador rs11629841 con los juicios ortográficos de los niños a las edades de 7 y 8 años (todos los valores de P <0,020). También se observaron asociaciones significativas con el dictado de caracteres chinos (todos los valores de P <0,013) para este polimorfismo de un solo nucleótido (SNP) a los 9, 10 y 11 años. Otros análisis revelaron que la asociación con las habilidades ortográficas era específica para el procesamiento de componentes específicos de los caracteres (valores de P <0,046). No se encontró asociación en ninguno de los SNP de rs3743205 o rs57809907. Nuestros hallazgos sugieren que DYX1C1 influye en el desarrollo de la lectura en la población general china y respalda un efecto universal de este gen.

Several independent studies have supported the association of DYX1C1 with dyslexia, but its role in general reading development remains unclear. Here, we investigated the contribution of this gene to reading, with a focus on orthographic skills, in a sample of 284 unrelated Chinese children aged 5 to 11 years who were participating in the Chinese Longitudinal Study of Reading Development. We tested this association using a quantitative approach for Chinese character reading, Chinese character dictation, orthographic judgment, and visual skills. Significant or marginally significant associations were observed at the marker rs11629841 with children's orthographic judgments at ages 7 and 8 years (all P values<0.020). Significant associations with Chinese character dictation (all P values<0.013) were also observed for this single-nucleotide polymorphism (SNP) at ages 9, 10, and 11 years. Further analyses revealed that the association with orthographic skills was specific to the processing of specific components of characters (P values<0.046). No association was found at either SNP of rs3743205 or rs57809907. Our findings suggest that DYX1C1 influences reading development in the general Chinese population and supports a universal effect of this gene.

دعمت العديد من الدراسات المستقلة ارتباط DYX1C1 بعسر القراءة، لكن دوره في تطور القراءة العام لا يزال غير واضح. هنا، قمنا بالتحقيق في مساهمة هذا الجين في القراءة، مع التركيز على المهارات الإملائية، في عينة من 284 طفلًا صينيًا غير مرتبطين تتراوح أعمارهم بين 5 و 11 عامًا كانوا يشاركون في الدراسة الطولية الصينية لتنمية القراءة. اختبرنا هذا الارتباط باستخدام نهج كمي لقراءة الأحرف الصينية، وإملاء الأحرف الصينية، والحكم الإملائي، والمهارات البصرية. لوحظت ارتباطات كبيرة أو هامشية في علامة rs11629841 مع الأحكام الإملائية للأطفال في سن 7 و 8 سنوات (جميع قيم P <0.020). كما لوحظت ارتباطات كبيرة مع إملاء الحرف الصيني (جميع قيم P <0.013) لهذا تعدد الأشكال أحادي النوكليوتيد (SNP) في سن 9 و 10 و 11 عامًا. كشفت المزيد من التحليلات أن الارتباط بالمهارات الإملائية كان خاصًا بمعالجة مكونات محددة من الأحرف (قيم P <0.046). لم يتم العثور على أي ارتباط في SNP من rs3743205 أو rs57809907. تشير النتائج التي توصلنا إليها إلى أن DYX1C1 يؤثر على تطور القراءة لدى عامة السكان الصينيين ويدعم التأثير العالمي لهذا الجين.
