High levels of trait anxiety confer an elevated risk for the development of anxiety and other psychiatric disorders. There is evidence that 5-hydroxytryptamine receptor 1B (5-HT1B) gene polymorphisms play an important role in emotional disorders. Genotyping for four single-nucleotide polymorphisms (SNP) (rs11568817, rs130058, rs6297, and rs13212041) was conducted for 388 high trait anxious (HTA) individuals and 463 low traitanxious (LTA) individuals in Chinese Han college subjects. The results showed that the frequencies of the C-allele and TC + CC genotype of rs13212041 in the LTA individuals were higher than that in the HTA individuals (p = 0.025 and p = 0.014, respectively). Both the C-allele and TC + CC genotype were associated with trait anxiety decreasing (OR = 0.771 and OR = 0.71, respectively). Furthermore, different gene model analysis also showed that the C allele was a protective factor for trait anxiety in Chinese Han college subjects. These findings suggest that 5-HT1B rs13212014 may play a role in trait anxiety among China Han college subjects. The rs13212014 polymorphism may be involved in decreasing the risk of trait anxiety. These results also provide a novel insight into the molecular mechanism underlying trait anxiety.<\/jats:p>","DOI":"10.3390\/life11090882","type":"journal-article","created":{"date-parts":[[2021,8,30]],"date-time":"2021-08-30T22:49:51Z","timestamp":1630363791000},"page":"882","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Association between 5-Hydroxytryptamine Receptor 1B rs13212041 Polymorphism and Trait Anxiety in Chinese Han College Subjects"],"prefix":"10.3390","volume":"11","author":[{"given":"Xiaofei","family":"Ruan","sequence":"first","affiliation":[{"name":"Key Laboratory of Modern Teaching Technology, Ministry of Education, Xi\u2019an 710062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suwen","family":"Fang","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Senqing","family":"Qi","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingfang","family":"Tian","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Teaching Technology, Ministry of Education, Xi\u2019an 710062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Ren","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Teaching Technology, Ministry of Education, Xi\u2019an 710062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1016\/j.neuron.2010.12.034","article-title":"Fear-conditioning mechanisms associated with trait vulnerability to anxiety in humans","volume":"69","author":"Indovina","year":"2011","journal-title":"Neuron"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"312","DOI":"10.1016\/j.tins.2009.02.004","article-title":"From high anxiety trait to depression: A neurocognitive hypothesis","volume":"32","author":"Sandi","year":"2009","journal-title":"Trends Neurosci."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1348\/014466599162845","article-title":"Attentional bias for emotional faces in generalized anxiety disorder","volume":"38","author":"Bradley","year":"1999","journal-title":"Br.
