RIMBP2 and bruxism: The second region was identified on chromosome 12, near the RIMS Binding Protein 2 (RIMBP2) gene (Figure 3b); individuals carrying the T allele of the top SNP rs571497947 had a risk of bruxism 3.495 times higher than individuals with the TGGGGGGA allele sequence (Table 3 and Figure 3e).
