Abstract

Aim: To find out the association of secreted protein acidic and rich in cysteine (SPARC)-related modular calcium binding 2 (SMOC2) gene variants rs2255680 and rs13208776 with genotypic and phenotypic characteristics in both familial and non-familial primary open angle glaucoma (POAG) patients.

Methods: A total of 212 POAG patients, comprising 124 familial and 88 non-familial, were enrolled. For genotyping the SMOC2 variant rs2255680, amplification refractory mutation system (ARMS)-polymerase chain reaction (PCR) method and PCR-restriction fragment length polymorphism (PCR-RFLP) were utilized for analyzing rs13208776 variant.

Results: The mean age of familial POAG patients was 50.92±9.12y, with 78 males and 46 females. The mean age of non-familial POAG patients was 53.14±13.44y, with 52 males and 36 females. The SMOC2 gene variant rs13208776 showed the significant association with POAG between familial and non-familial groups. The homozygous G/G variant was frequent among non-familial (60.2%) whereas the heterozygous G/A variant was more frequent in familial POAG patients (46%). There were significant differences in G/A variant between familial and non-familial glaucoma patients, and the risk was decreased to 0.53-fold in non-familial glaucoma patients [odds ratio (OR): 0.53; 95% confidence interval (CI): 0.29-0.94; P=0.033] in codominant model. The risk was further reduced to 0.49-fold (95%CI: 0.28-0.86; P=0.012) in dominant model for non-familial patients. No significant association of SMOC2 gene variant rs2255680 between familial and non-familial glaucoma patients was found in our population. The haplotype analysis showed the decreased risk for TA [OR: 0.48 (95%CI: 0.29-0.79); P=0.004] and an increased risk for TG [OR=2.28 (95%CI: 1.22-4.25); P=0.01] haplotypes.

Conclusion: Current findings show significant association of SMOC2 gene variant rs13208776 with POAG between familial and non-familial Pakistani patients.

巴基斯坦家族性与非家族性原发性开角型青光眼SMOC2基因变异分析。

目的：探讨家族性和非家族性原发性开角型青光眼（POAG）患者分泌蛋白酸性和富含半胱氨酸（SPARC）相关的模块化钙结合2 （SMOC2）基因变异rs2255680和rs13208776与基因型和表型特征的关系。方法：共纳入212例POAG患者，其中家族性124例，非家族性88例。采用扩增难解突变系统(ARMS)-聚合酶链反应（PCR）法和限制性片段长度多态性（PCR- rflp）法对SMOC2变异rs2255680进行基因分型。结果：家族性POAG患者平均年龄为50.92±9.12y，其中男性78例，女性46例。非家族性POAG患者的平均年龄为53.14±13.44y，男性52例，女性36例。SMOC2基因变异rs13208776在家族性和非家族性人群中与POAG显著相关。纯合子G/G变异常见于非家族性POAG患者（60.2%），而杂合子G/A变异常见于家族性POAG患者（46%）。家族性和非家族性青光眼患者的G/A变异有显著性差异，非家族性青光眼患者的风险降低至0.53倍[优势比（OR）： 0.53；95%置信区间（CI）： 0.29-0.94；P=0.033]。风险进一步降低至0.49倍(95%CI: 0.28-0.86；P=0.012)。在我们的人群中没有发现家族性和非家族性青光眼患者与SMOC2基因变异rs2255680有显著关联。单倍型分析显示TA风险降低[OR: 0.48 (95%CI: 0.29-0.79)；P=0.004]和TG风险增加[OR=2.28 (95%CI: 1.22-4.25)；单P = 0.01)。结论：目前的研究结果表明，在家族性和非家族性巴基斯坦患者中，SMOC2基因变异rs13208776与POAG有显著相关性。
