Tyw3 is a gene encoding a S - adenosylmethionine (SAM)-dependent methyltransferase. It is responsible for the formation of a tRNA modification known as wybutosine and its derivatives, which are crucial for accurate decoding in protein synthesis [2]. It is also associated with pathways related to insulin resistance and may be involved in the pathogenesis of diseases such as amyotrophic lateral sclerosis (ALS) [1].

In a genome - wide association study in the Chinese Han population, TYW3/CRYZ was identified as a susceptibility gene for ALS, suggesting that insulin resistance might be implicated in ALS pathogenesis [1]. A genome - wide association study on circulating resistin levels found that genetic variants in the TYW3/CRYZ locus may be involved in the regulation of circulating resistin levels, and the resistin - rising allele of a SNP in this locus was associated with an increased coronary heart disease risk [3]. In esophageal cancer, TYW3 was one of the five prognostic RNA - binding proteins identified, with its down - regulation in tumor samples [4].

In conclusion, Tyw3 plays an essential role in tRNA modification for accurate protein synthesis. Its association with diseases like ALS, coronary heart disease, and esophageal cancer, as revealed through genetic association studies, indicates its significance in understanding disease pathogenesis. These findings from model - based research contribute to exploring potential disease mechanisms and developing new strategies for diagnosis and treatment in these disease areas.
