Abstract

Background & objective: Hypovitaminosis D has shown to be linked with T2DM development and control in numerous studies. The association of SNPs in genes related to VitD metabolism with T2DM has not been sufficiently studied. Consequently, our aim in the present study was to explore the association between genetic variants in genes connected with VitD, mainly a SNP in GC (rs1155563), a SNP in DHCR7 (rs12785878) and a SNP in CYP2R1 (rs10500804) with glycaemic parameters in females with T2DM in Saudi Arabia.

Methods: The cross-sectional study included 149 females (age 38-52 years) with T2DM from Jeddah, Saudi Arabia (September 2022-March 2023). Blood was extracted from the participants for biochemical tests including measuring VitD [25(OH)D] concentration, parameters of glycaemia (HbA1c, insulin, fasting glucose and insulin sensitivity indices including HOMA2-IR and HOMA2-%β), and for genomic DNA isolation. Sanger DNA sequencing was used to screen for VitD genetic polymorphisms (rs1155563, rs12785878 and rs10500804).

Results: Minor allele frequency for rs1155563C, rs12785878T and rs10500804G was 0.21, 0.23 and 0.37, respectively. Levels of 25(OH)D and glycaemic parameters as well did not show any significant difference between the genotypes of each SNP.

Conclusion: This study showed lack of association of rs1155563 in GC, rs12785878 in DHCR7 and rs10500804 in CYP2R1 with VitD level primarily and with glycaemic parameters secondarily. Additional research is required to explore further other VitD genetic polymorphisms influencing T2DM which might lead consequently to genetically-based personalized management for T2DM.

沙特阿拉伯 2 型糖尿病女性患者中维生素 D 代谢基因（rs1155563、rs12785878 和 rs10500804）的遗传变异。

背景和目的：大量研究表明，维生素 D 不足与 T2DM 的发生和控制有关。有关维生素 D 代谢基因的 SNPs 与 T2DM 的关系尚未得到充分研究。因此，本研究旨在探讨沙特阿拉伯 T2DM 女性患者中与 VitD 相关基因的遗传变异（主要是 GC 中的一个 SNP（rs1155563）、DHCR7 中的一个 SNP（rs12785878）和 CYP2R1 中的一个 SNP（rs10500804））与血糖参数之间的关系：这项横断面研究纳入了沙特阿拉伯吉达市的 149 名 T2DM 女性患者（38-52 岁）（2022 年 9 月至 2023 年 3 月）。研究人员抽取参与者的血液进行生化测试，包括测量维生素 D [25(OH)D] 浓度、血糖参数（HbA1c、胰岛素、空腹血糖和胰岛素敏感性指数，包括 HOMA2-IR 和 HOMA2-%β），并分离基因组 DNA。利用 Sanger DNA 测序筛选 VitD 基因多态性（rs1155563、rs12785878 和 rs10500804）：结果：rs1155563C、rs12785878T 和 rs10500804G 的小等位基因频率分别为 0.21、0.23 和 0.37。各 SNP 基因型之间的 25(OH)D 水平和血糖参数也无显著差异：本研究表明，GC 中的 rs1155563、DHCR7 中的 rs12785878 和 CYP2R1 中的 rs10500804 主要与维生素 D 水平无关，其次才与血糖参数有关。还需要进行更多的研究，以进一步探索影响 T2DM 的其他 VitD 基因多态性，从而对 T2DM 进行基于基因的个性化管理。

期刊介绍： It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
