Review of Genetic Variants of Butyrylcholinesterase and Their Potential Impact on Human Health

Butyrylcholinesterase (BChE) is an enzyme found in plasma and many other parts of the body. It is enzyme that hydrolyses drugs containing ester bonds such as drugs acting at the neuromuscular junction (succinylcholine) and local anaesthetics (procaine). Examination of the gene for mutations or polymorphisms causing the observed biochemical phenotypes has isolated those responsible for all the most widely known variants. The molecular bases of several genetic variants of BChE have been reported, such as the Atypical variant, fluoride-resistant variant, silent variant, K variant, J variant and C5 variant. In general, BChE polymorphisms have been shown to produce enzymes with varying levels of catalytic activity. Genetic variants of human butyrylcholinesterase were one of the first examples in the new field of pharmacogenetics when it was recognized that abnormal response to the succinylcholine was due to a mutated enzyme with low binding affinity. Beside that, variant of BChE has potential impact for Alzheimer disease patology.

A Forkhead box G1 (FOXG1) gene mutation in an Indian patient with a congenital variant of Rett syndrome.

A congenital variant of rett syndrome or Forkhead box G1 (FOXG1) syndrome is a rareneurodevelopmental disorder characterized by global developmental delay, microcephaly, autisticfeatures, early-onset dyskinesia, and seizures. Once it was described as one atypical variant of rettsyndrome but now considered as a separate entity. The current study found one girl carrying the denovo c.500-501incG frameshift mutation in the FOXG1 gene by genetic analysis during theevaluation for severe chronic encephalopathy. In literature, only one case was reported from Indiawith FOXG1 mutation. The FOXG1 mutation should be considered in children with a history of globaldevelopmental delay, dyskinesia, and microcephaly with characteristic brain neuroimaging findings.

THE VARIANT ANATOMY OF THE CELIAC TRUNK AND ITS BRANCHES IN ADULT MEN AND WOMEN WITH VARIOUS BODY SHAPE

In connection with the rapid development of endovascular surgery and the increasing number of minimally invasive surgeries there is a need for a detailed study of variants of the architectonic and topographic and anatomical characteristics of extraorganic blood vessels. The purpose of the study was to study the variant anatomy of the celiac trunk and its branches in adult men and women with different shapes of body. The analysis of 2300 computer tomograms of the abdominal aorta and its unpaired branches of adult men and women in age 25-75 years with a different body type was made. According to the value of the Pinier index, were dedicated asthenic, normosthenic and hypersthenic forms of the physique. It is established that the cases of a typical classic variant of celiac trunk trifurcation in men is observed only in 35% of cases, and in women – in 41.2%, with an atypical variant of its division was observed significantly more often (in 65 and 58,8%, respectively). It is shown that regardless of gender and the shape of the body at Pinier index in all studied groups, the incidence of typical branching of the celiac trunk varies from 32.1 to 49.4%, and the frequency of atypical variant is an average of 62.1%. Among atypical variants of division of the celiac trunk quadrifurcation occurs more often. Thus, the frequency of most of the variants of the celiac trunk showed significant differences depending on gender and body type. Knowledge of variant anatomy of the celiac trunk will be may significantly increase the quality of preoperative diagnosis in surgery on the celiac trunk and its branches, and exclude iatrogenic damage of these vessels.
