Whole exome sequencing revealed a pathogenic variant in a gene related to malignant hyperthermia in a Vietnamese cardiac surgical patient: A case report

Abstract: IntroductionMalignant hyperthermia (MH) is a rare autosomal dominant pharmacogenetic disorder which known associated with some genes such as CACNA1S and RYR1. Using whole exome analysis, we aimed to find out the genetic variant data in a malignant hyperthermia patient undergoing cardiac surgery.Presentation of casePatient was 59 years old male with dull left chest pain, mild breathing difficulty, thrombosis in the left atrium, mitral valve stenosis that needed a surgery to remove the thrombus and replace the m… Show more

“…A comprehensive analysis by traditional Sanger sequencing is challenging because it is costly, time-consuming, and labor-intensive, without even considering other possible genes in the genome [ 7 , 9 , 10 ]. Next-generation sequencing (NGS) analysis can help delineate the genetic diagnosis of MH and several MH-susceptible clinical presentations [ 41 , 42 ]. Moreover, the use of NGS in unselected cohorts is an important tool to understand the prevalence and penetrance of MH susceptibility, a critical challenge in the field [ 43 , 44 ].…”

“…Thêm vào đó, nghiên cứu của Merrit và cộng sự đã công bố thêm 5 biến thể khác (p.Arg2336His, p. Arg2355Trp, p. Glu3014Lys, p.Gly3990Val và p.Val4849Ile) được sử dụng trong chẩn đoán di truyền xác định nhạy cảm với TTNAT [21]. Trong nghiên cứu mới công bố năm 2019, nhóm nhà khoa học tại Đại học Quốc gia Hà Nội đã chỉ ra vai trò của đa hình c.7048G>A (p.Ala2350Thr) gen RYR1 trên một ca lâm sàng tăng thân nhiệt ác tính sau phẫu thuật thay van tim [23].…”
