遺伝子研究の概要
Slc5a5, also known as the sodium/iodide symporter (NIS)-coding gene, is crucial for transporting iodide into thyroid follicular cells, a key step in thyroid hormone synthesis [1,2,3,4,5,6,7,8]. This process is integral to the thyroid-pituitary axis pathway, which is essential for maintaining normal physiological functions in the body. Genetic models, such as those studying gene variants, can provide insights into its function [1,4,5,6,7].
Mutations in Slc5a5 can lead to various thyroid-related disorders. Loss-of-function variants in this gene are associated with congenital iodide transport defect (ITD), a cause of dyshormonogenic congenital hypothyroidism [1,5,6]. For example, a novel homozygous synonymous variant (c.1326A>C) was found to cause aberrant NIS pre-mRNA splicing, expanding the mutational landscape of Slc5a5-related congenital hypothyroidism [1]. In a Chinese patient, novel compound heterozygous mutations (p.Gly51AlafsTer45 and p.Gly421Arg) led to reduced NIS expression and impaired iodide transport function [4]. A novel missense p.G561E NIS variant reduced iodide uptake by impairing the recognition of a motif by kinesin light chain 2, affecting NIS maturation [5]. Two novel compound heterozygous SLC5A5 variants (p. [Gln263Leu]; [Gly350Asp]) in a Japanese sibling also caused negligible iodide transport capacity [6].
In conclusion, Slc5a5 is essential for thyroid hormonogenesis through its role in iodide transport. Studies on gene variants in this gene have revealed its significance in congenital hypothyroidism and other thyroid-related diseases. Understanding the function of Slc5a5 through genetic models contributes to a better understanding of the molecular mechanisms underlying these diseases, potentially guiding future diagnostic and therapeutic strategies.
