HTR2C
Risk or phenotype-associated allele: T. Phenotype: The T allele was more frequently found in subjects not gaining 10% or more of their body weight, compared with those who did gain 10% or more of their body weight. None of the subjects who gained >10% of their initial body weight over 6 weeks carried a T allele (0/11). Study size: 42. Study population/ethnicity: Caucasian acutely ill patients with schizophrenia taking olanzapine. Significance metric(s): p = 0.0035. Type of association: CO.- Variant Name:
- HTR2C:-759C/T; HTR2C:-759C>T
- Related Drugs:
- olanzapine
