Background: Post-stroke fatigue (PSF) is a common sequela of stroke. Despite reports of serotonergic involvement in the etiology of PSF, the potential contribution of serotonergic genes in the development of PSF needs to be investigated. Methods: A total of 373 patients, who experienced ischemic stroke for PSF, were evaluated 3 months after the stroke. PSF was assessed using the Fatigue Severity Scale. The genomic DNA collected and stored in a -70°C freezer was genotyped for 6 polymorphisms in genes associated with serotonin synthesis (tryptophan hydroxylase 1 (TPH1) A218C, TPH2 rs10879355, and TPH2 rs4641528), transport (the promoter region of the serotonin transporter protein), and catabolism (the 30-bp functional variable number tandem repeat) polymorphism in the promoter region of monoamine oxidase A (MAO-A). Results: Among the 373 patients, 164 (44%) had PSF. All patients were ethnic Koreans. Of the 6 polymorphisms examined, only one marker, that is, low-activity MAO-A was associated with PSF (p < 0.05) in female patients. Multiple logistic regression analyses showed that post-stroke depression (PSD; 95% CI 1.561-14.323, p = 0.006) and low MAO-A activity (95% CI 0.166-0.722, p = 0.005) were factors associated with PSF in female patients, whereas only PSD (95% CI 5.511-65.269, p = 0.000) was associated with PSF in male patients. Conclusions: Our findings suggest that PSF may be associated with a genetic polymorphism involving MAO-A, at least in female stroke patients.

Abstract Introduction The etiology of sudden infant death syndrome (SIDS) remains an unsolved problem. The aim of this meta-analysis is to investigate the potential association between monoamine oxidase A (MAOA) promoter variable number tandem repeat (VNTR) polymorphism and SIDS risk. Methods A systematic review and meta-analysis were conducted on studies from accessible electronic databases. Each VNTR variant was examined in each gender independently by comparing with the pooled results of other alleles. Results A total of six independent case–control studies including 1022 SIDS cases and 1839 controls were enrolled in this meta-analysis. In both of the whole populations and Caucasian populations, male infants with the low-MAOA-expression alleles (2R+3R) were found to exhibit a statistically significant increased risk of SIDS, whereas those with a 4R allele exhibited a reduced risk of SIDS. Besides, an increased risk of SIDS was detected in male Caucasian infants with 2R or 3R alleles. However, none of the allele or genotype variants was associated with SIDS in female victims. Conclusion In male Caucasian infants, the low expression of MAOA promoter VNTR alleles (2R and 3R) is associated with an increased risk of SIDS, and the existence of the 4R allele could be regarded as a protective factor.
