SYNPO2L gene rare variants in the development of early myocardial infarction
https://doi.org/10.25557/2073-7998.2024.06.20-28
Abstract
Myocardial infarction (MI), being the main complication of coronary heart disease (CHD), is one of the most common causes of death and disability in the adult population. Currently, there is an increase in the incidence of MI at a young age. An independent risk factor for MI at a young age is hereditary predisposition. In this work, we searched for rare genetic variants associated with the development of cardiovascular diseases using whole-exome sequencing in patients who had suffered an MI before the age of 45 years, and for whom the main genetic risk factors for MI − monogenic dyslipidemias and thrombophilia – were excluded. In two patients, rare variants of the SYNPO2L gene were identified − p.(Arg630Leu) (rs143723429) and a previously undescribed variant p.(Arg910Gln), leading to amino acid substitutions that can lead to dysfunction of the corresponding protein. The data obtained suggest the involvement of the SYNPO2L gene, encoding a protein of contractile muscle function, in the pathogenesis of early MI.
