  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>Central corneal thickness (CCT) is a highly heritable trait associated with complex eye diseases such as keratoconus and glaucoma. We perform a genome-wide association meta-analysis of CCT and identify 19 novel regions. In addition to adding support for known connective tissue-related pathways, pathway analyses uncover previously unreported gene sets. Remarkably, &gt;20% of the CCT-loci are near or within Mendelian disorder genes. These included <jats:italic>FBN1</jats:italic>, <jats:italic>ADAMTS2</jats:italic> and <jats:italic>TGFB2</jats:italic> which associate with connective tissue disorders (Marfan, Ehlers-Danlos and Loeys-Dietz syndromes), and the <jats:italic>LUM-DCN-KERA</jats:italic> gene complex involved in myopia, corneal dystrophies and cornea plana. Using index CCT-increasing variants, we find a significant inverse correlation in effect sizes between CCT and keratoconus (<jats:italic>r</jats:italic> = −0.62, <jats:italic>P</jats:italic> = 5.30 × 10<jats:sup>−5</jats:sup>) but not between CCT and primary open-angle glaucoma (<jats:italic>r</jats:italic> = −0.17, <jats:italic>P</jats:italic> = 0.2). Our findings provide evidence for shared genetic influences between CCT and keratoconus, and implicate candidate genes acting in collagen and extracellular matrix regulation.</jats:p>
