Isolated left ventricular noncompaction (LVNC) is a form of cardiomyopathy that most commonly presents in infancy with a hypertrophic and dilated left ventricle characterized by deep trabeculations and intertrabecular recesses. Our goal was to determine the frequency of mutations in G4.5, alpha-dystrobrevin, and FK Binding protein-12 in isolated LVNC patients. No mutations were identified in 47 of the 48 patients studied, while a splice site acceptor site mutation of intron 10 of G4.5 was identified in one patient, resulting in the deletion of exon 10 from the mRNA.
孤立性左心室心肌致密化不全(LVNC)是一种心肌病,最常见于婴儿期,表现为肥厚和扩张的左心室,其特征为深陷的肌小梁和小梁间隐窝。我们的目标是确定孤立性LVNC患者中G4.5、α-肌营养不良蛋白和FK结合蛋白-12的突变频率。在研究的48例患者中,47例未发现突变,而在1例患者中发现了G4.5第10内含子的剪接受体位点突变,导致mRNA中外显子10缺失。
