This in turn can lead to more widespread collapse of the nasal skeleton. Nose-picking is a common, mildly taboo habit. Medical risks include the spread of infections, nosebleeds and, rarely, perforation of the nasal septum. When it becomes compulsive it is termed rhinotillexomania. The wiping of the nose with the hand, commonly referred to as the "allergic salute", is also mildly taboo and can result in the spreading of infections as well. Habitual as well as
Cause of obsessive-compulsive disorder OCD in a Han Chinese population and found that one SNP, rs10491734, was significantly more frequent in OCD patients than in controls. However, the exact SNPs identified in the different studies vary, though it is possible that this is because the studies were conducted on different ethnic populations. For example, a family-based association study analyzed the instances of SNPs in and around SLC1A1 in families from throughout the US and found that a different SNP, rs4740788, and a 3-SNP haplotype, rs4740788-rs10491734-rs10491733, were both related to OCD. Several mouse models have been developed for the study of obsessive-compulsive disorder. Model organisms
