      Background: Variations in the TSHR gene have been implicated in a spectrum of thyroid diseases. Previous studies have implicated variations in the TSHR gene, including SNPs rs179247, rs12101255, and rs2268458, in thyroid diseases, but their association with hypothyroidism and hyperthyroidism in the Indian population has not been investigated. Aim: In this study, we aimed to examine the relationship between candidate SNP rs2268458 and susceptibility to hypothyroidism and hyperthyroidism in the Indian population. We carried out a case–control genetic screening of the TSHR gene. Methods: We analyzed the variant of the TSHR gene using the PCR–RFLP technique in a total of 318 participants, including 130 controls and 188 individuals with thyroid disorders (124 hypothyroid and 64 hyperthyroid). Demographic information was collected, and biochemical parameters were assessed using enzymatic methods. Statistical analysis was performed using SPSS-23. Results: The SNP rs2268458 demonstrated a significant association with hypothyroid and hyperthyroid patients (p-value < 0.05). Using the dominant genetic model, we calculated an odds ratio of 3.52 (confidence interval: 2.09–5.93, p-value: 0.0001) for the risk of hypothyroidism and an odds ratio of 2.34 (confidence interval: 1.26–4.31, p-value: 0.0001) for the risk of hyperthyroidism. Conclusion: This pioneering study in the Indian population reveals a significant association between the C allele of TSHR gene SNP rs2268458 and an increased risk of developing both hypothyroidism and hyperthyroidism. Our findings suggest that the C allele may be a common genetic risk factor for thyroid dysfunction in Indians. [ABSTRACT FROM AUTHOR]

      المقال يركز على العلاقة بين تعدد أشكال جين TSHR (تحديدًا SNP rs2268458) وقابلية الإصابة بخلل الغدة الدرقية، بما في ذلك قصور الغدة الدرقية وفرط نشاط الغدة الدرقية، في السكان الهنود. أظهرت دراسة حالة-شاهد شملت 318 مشاركًا وجود ارتباط كبير بين الأليل C لجين TSHR وزيادة خطر الإصابة بكلا الاضطرابين في الغدة الدرقية، حيث تشير نسب الأرجحية إلى احتمال أعلى لتطور قصور الغدة الدرقية (3.52) وفرط نشاط الغدة الدرقية (2.34) بين حاملي الأليل C. تشير النتائج إلى أن الاختبارات الجينية لهذا SNP قد تكون مفيدة في التشخيص السريري وإدارة أمراض الغدة الدرقية في الهند.
