Abstract

Purpose : Myopia has two important endophenotypes, axial length (AL) and spherical equivalent (SE), all previous myopia related genome-wide association studies (GWASs) were analyzing AL or SE alone. We conducted a mulitvairate GWASs by jointly analyzing AL and SE for myopia in Asian cohorts from a subset of CREAM consortium.

Methods : The univariate regression modeling for the Orthogonal Decomposition Analysis (RegODA) method was used in our multivariate GWASs. We performed a multivariate meta-analysis of genome-wide association studies on AL and SE in Chinese children from the Guangzhou Twin Eye Study (GTES n=1055) and Singapore Cohort Study of the Risk Factors for Myopia (SCORM, n=915) and 6795 Asian adults from Singapore Epidemiology of Eye Disease (SEED), and Singaporean Chinese in the Strabismus, Amblyopia, and Refractive Error Study (STARS).

Results : We identified three novel genes associated with myopia: CMPK1 derived from SNP rs60078183 (P=3.77×10-8), PARPBP derived from SNP rs11204213 (P=1.52×10-8), and ZNF488 derived from SNP rs11111226 (P=2.67×10-8). Interestingly, we found that the signals from these three novel genes were mainly origin from AL , but not significant in SE.

Conclusions : In this mutlvairate genome-wide meta-analyses, we found three novel genes for myopia in Asia. More studies were needed for validation of our study findings.
