- rs5443(T) allele carriers are 2-3 fold more likely to be obese in Caucasian, Chinese, and African American populations. [PMID 10477144]
- rs5443(T) carriers are clearly at higher risk for hypertension, but this review indicates that whether they are also at increased risk for stroke and left ventricular hypertrophy remains controversial. [PMID 12530935]
- rs5443(T;T) women gain significantly more weight during pregnancy than rs5443(C;T) or rs5443(C;C) women, and had a significantly higher pre-pregnancy body mass index. [PMID 12668921]
- rs5443(T;T) genotypes respond to Viagra better. 91% of them have a "positive erectile response" upon taking Viagra, whereas only around 50% of rs5443(C;T) and rs5443(C;C) individuals respond equivalently to the drug. The odds ratio for the positive response was 10.0 (CI: 1.2 - 81.1, p = 0.01). [PMID 12576843]
- rs5443(T;T) patients receiving clozapine over a long term for the treatment of schizophrenia gain significantly more weight (16%) compared to patients carrying at least one rs5443(C) allele in a study of Chinese patients. [PMID 16141801]
- rs5443(T) carriers taking triptans for the treatment of migraines or cluster headaches were ~3 fold more likely to respond positively compared with rs5443(C;C) homozygotes (OR 2.96, CI:1.34 - 6.56, p=0.0074) in a study of ~200 Caucasian patients. [PMID 17361120]
- rs5443(C;T) genotypes are more prevalent in gastroesophageal reflux disease (GERD) patients relative to healthy controls (odds ratio 1.43, CI: 1.04–1.98).[PMID 19174793]
- rs5443(C;C) individuals do not lose weight under sibutramine therapy whereas (C;T) and (T;T) individuals do, based on a study of 131 obese Taiwanese patients.[PMID 19687782] 23andMe blog
