Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract The purpose of this research was to determine the frequency of mutation of the cytochrome CYP3A5 genes and transport proteins SLCO1B1 and MDR1 in patients with coronary heart disease in the Kazakh nation. A prospective cohort clinical and genetic study was conducted. The study was conducted in 2017−2019. Medical records containing information about drug prescription conducted in hospitals and outpatient departments were carefully analyzed. In the examined group of 178 patients treated with statins, a significant frequency of genetic variants that determine the increased risk of complications of statin use was revealed. There was a tendency toward an increase in the activity of creatine phosphokinase (CPK) in the blood upon detection of the A6986G mutation of the cytochrome gene and SLCO1B1 (c.521T>C) gene of the transport protein OATP1B1. In the studied Kazakh population, the presence of a homozygous mutant SLCO1B1 gene of the transport protein can be recommended as a genetic marker for the undesirability of using antihypercholesterolemic therapy with statins, which simultaneously leads to a decrease in the effectiveness of treatment and an increase in the risk of side effects.
