AVPR1A Antibody

1. Study finds evidence of differential allele expression, in at least a third of human brain samples heterozygous for a reporter single nucleotide polymorphism (SNP) in the arginine vasopressin receptor 1a (AVPR1a) transcript. We also show that this functional effect and a downstream phenotype, externalizing behavior, are predicted by AVPR1a short tandem repeats but not SNPs. PMID: 29581423
2. Despite having a similar minor allele frequency (MAF) of 14.5% compared with the SMILE cohort, our results did not support an association of the mirSNP rs11174811 with the hypertension phenotype or with continuous blood pressure outcomes in the south Indian population. PMID: 29182374
3. The data of this study indicated that alterations in amygdala signalling may constitute a neural mechanism by which polymorphisms of the AVPR1A gene could influence ASD susceptibility. PMID: 28322981
4. These results demonstrate that polymorphisms in the AVPR1A promoter region might be involved in pathophysiology of ASD and in functional regulation of the expression of AVPR1A. PMID: 28808521
5. Overall, our study establishes continuity between the existing AVPR1a research in clinical and non-clinical populations. Our results suggest that vasopressin may exert its effects on social behaviour in part by modulating attentional focus between social and non-social cues. PMID: 27874273
6. Three OXTR polymorphisms (rs2270465, rs2268493, rs7632287) and 2 AVPR1A polymorphisms (rs1587097, rs1042615) showed nominal effects (p < .05) on vocal symptoms, of which 1 (rs1587097) remained significant after correcting for multiple testing (p = .003). Study found potential mediation of the effect of the OXTR rs2268493 polymorphism on vocal symptoms through levels of cortisol. PMID: 28687839

15. AVPR1A RS3 was not associated with schizophrenia; variation in the AVPR1A gene contributes to social behavioral deficits associated with schizophrenia PMID: 25529259
16. Study identified, in OXTR and AVPR1A genes, signatures of balancing selection in the cis-regulative acting sequences such as transcription factor binding and enhancer sequences, as well as in a transcriptional repressor sequence motif. Additionally, in the intron 3 of the OXTR gene, the SNP rs59190448 appears to be under positive directional selection. PMID: 25968600
17. Haplotype analysis revealed an association of AVPR1A C*S- and C*L-haplotype (rs11174811 and RS1, respectively) and increased or decreased Extraversion (EPI) in Bashkirs, respectively. PMID: 25438555
18. Study found that variability in the rs7298346 marker, located in the 5'-flanking region, was related to a composite measure of executive functioning in 4-year-old children after controlling for a variety of covariates and children's theory of mind. PMID: 25016245
