It helps in the secretion of triiodothyronine (T3) and tetraiodothyronine (T4). Polymorphisms in SLC5A5 result in hypothyroidism. The aim of the study is to estimate the frequency of rs7250346, a single nucleotide polymorphism (SNP) associated with thyroid disease, in a Saudi population and to compare it to other populations. <br><br><strong>Methods:</strong> Two hundred and forty Saudi patients from King Faisal Specialist Hospital and Research Centre provided samples for the genetic analysis. Samples were genotyped for target SNPs by real time polymerase chain reaction (PCR), and the resultant rs7250346 frequency in the Saudi population was compared to other populations using HapMap. <br><br><strong>Results:</strong> Out of the 240 Saudi samples, 64% had C genotype and 35% had G genotype in the rs7250346. Conclusion: The Saudi frequency of the rs7250346 SNP of SLC5A5 differs from that of European, Chinese, Japanese, or Sub-Saharan populations in HapMap (<a href="http://hapmap.org">http://hapmap.org</a>).</p> ER -
