TITRE DE L’ÉTUDE: Une méta-analyse de 542934 sujets d’ascendance européenne identifie de nouveaux gènes et mécanismes prédisposant à l’erreur de réfraction et à la myopie
SOMMAIRE: Découverte de 336 nouvelles régions génomiques associées à des erreurs de réfraction, y compris la myopie.
APERÇU: Les erreurs de réfraction se produisent lorsque la forme de l’œil ne plie pas correctement la lumière, ce qui entraîne une vision floue ou floue. L’un des principaux types d’erreurs de réfraction est myopie , autrement connu sous le nom de myopie. Les erreurs de réfraction sont très courantes et la prévalence augmente, probablement en raison d’une combinaison de facteurs environnementaux et génétiques. En utilisant les données génétiques d’environ 550 000 individus d’origine européenne, cette étude a découvert 449 régions génomiques associées à l’erreur de réfraction, dont 336 sont nouvelles. Ensemble, les variantes génétiques identifiées expliquent 18,4% de l’héritabilité de l’erreur de réfraction. Les résultats suggèrent que l’erreur de réfraction est causée par des gènes impliqués dans le développement des yeux, la pigmentation et rythme circadien .
LE SAVIEZ-VOUS? La myopie, ou myopie, est une condition dans laquelle les objets à proximité sont clairs mais les objets à distance sont flous. Le moyen le plus courant de corriger la myopie consiste à porter des lunettes correctrices ou des lentilles de contact. On estime que plus d’un milliard d’individus dans le monde ont besoin de lunettes mais n’y ont pas accès, en particulier dans les pays en développement. L’inaccessibilité aux soins oculaires est un problème majeur de santé publique dans ces pays et a entraîné, entre autres, des accidents de la route et de mauvaises notes. [SOURCE]
