TY - JOUR T1 - Genotype–phenotype correlation and interaction of 4q25, 15q14 and <em>MIPEP</em> variants with myopia in southern Chinese population JF - British Journal of Ophthalmology JO - Br J Ophthalmol SP - 869 LP - 877 DO - 10.1136/bjophthalmol-2019-314782 VL - 105 IS - 6 AU - Junbin Liu AU - Riping Zhang AU - Lixia Sun AU - Yuqian Zheng AU - Shaowan Chen AU - Shao-Lang Chen AU - Yanxuan Xu AU - Chi-Pui Pang AU - Mingzhi Zhang AU - Tsz Kin Ng Y1 - 2021/06/01 UR - http://bjo.bmj.com/content/105/6/869.abstract N2 - Background/aims To determine the association and interaction of genome-wide association study-reported variants for Asian populations with myopia and ocular biometric parameters in southern Chinese population.Methods Totally, 1462 unrelated Han Chinese subjects were recruited with complete ophthalmic examinations, including 1196 myopia and 266 control subjects. A total of nine variants were selected for TaqMan genotyping. The genetic association, joint additive effect and genotype–phenotype correlation were investigated.Results The 4q25 variant rs10034228 (p=0.002, OR=0.56) and MIPEP variant rs9318086 (p=0.004, OR=1.62) were found to be significantly associated with myopia as well as different severity of myopia. Moreover, 15q14 variant rs524952 (p=0.015, OR=1.49) also showed mild association with myopia and high myopia. However, there was no significant association of CTNND2, vasoactive intestinal peptide receptor 2 and syntrophin beta 1 variants with myopia. Joint additive analysis revealed that the subjects carrying 6 risk alleles of the 3 associated variants were 10-fold higher risk predisposed to high myopia. Genotype–phenotype correlation analysis revealed that high myopia subjects carrying 4q25 rs10034228 T allele showed thicker central corneal thickness, whereas high myopia subjects carrying 15q14 rs524952 A allele were associated with longer axial length and larger curvature ratio.Conclusion This study revealed significant association of 4q25, 15q14 and MIPEP variants with myopia and different severity of myopia in southern Chinese population, joint additively enhancing 10-fold of risk predisposing to high myopia. The correlation of these associated variants with axial length and corneal parameters suggests their contribution to the refractive status in high myopia subjects.Data are available upon request. ER -
