[The association of NOS1AP gene polymorphisms with the duration of the QT interval in patients with schizophrenia receiving antipsychotic therapy].

OBJECTIVE

To study the associations of NOS1AP gene polymorphisms with the duration of the QT interval (QTc) in patients with schizophrenia receiving antipsychotics.

MATERIAL AND

METHODS

One hundred and sixty-eight patients (78 men and 90 women) with an established diagnosis of schizophrenia were examined. The patients received basic antipsychotic therapy. At the time of admission to the hospital, a standard 12-lead electrocardiogram recording was performed. The calculation of the QTc interval was carried out using the Bazett formula. Three NOS1AP polymorphisms (rs12029454, rs10494366 and rs12143842) were selected for genotyping.

RESULTS

Spearman's correlation revealed a significant relationship between CPZeq and the duration of the QTc interval in the group of men (rs=0.262; p=0.021; pBonf=0.042). CPZeq was positively correlated with the duration of the QTc interval in men with AA and AG rs12029454 (rs=0.717; p=0.00025; pbonf=0.0015), GG and GT rs10494366 (rs=0.381; p=0.008; pbonf=0.048), TT and CT rs12143842 (rs=0.389; p=0.003; pbonf=0.018) genotypes. We did not find any significant correlations in the group of women.

CONCLUSION

Genetic variants rs12029454, rs10494366 and rs12143842 of the NOS1AP gene are associated with the duration of the QTc interval in men with schizophrenia in response to antipsychotics. The AA/AG rs12029454, GG/GT rs10494366 and TT/CT rs12143842 genotypes in men contribute to the prolongation of the QTc interval and the development of undesirable cardiovascular disorders against the background of antipsychotic therapy.
