Abstract

We describe the phenotype of a patient with extensive aortic, carotid, and abdominal dissections. The proband was found to have a heterozygous deletion of exons 21-34 in , which is a rare finding, as deletions in this gene have been infrequently reported. We describe this finding following detection in a proband with an extensive history of aortic, carotid, and abdominal dissections. Neoteric molecular modeling techniques to help determine the impact of this deletion on protein function indicated loss of function due to lack of any kinase domain. We also provide the electrostatics calculations from the wild type and mutant variant. Through a combined multiomic approach of clinical, functional, and protein informatics, we arrive at a data fusion for determination of pathogenicity embedded within the genetic code for this particular genetic variant, which, as a platform, continues to broaden its scope across the field of variants of uncertain significance classification.

摘要

我们描述了一位患有广泛主动脉、颈动脉和腹部夹层的患者的表型。先证者被发现存在该基因外显子21 - 34的杂合缺失,这是一个罕见的发现,因为该基因的缺失很少被报道。我们在一位有广泛主动脉、颈动脉和腹部夹层病史的先证者中检测到这一发现后进行了描述。用于帮助确定该缺失对蛋白质功能影响的新型分子建模技术表明,由于缺乏任何激酶结构域,功能丧失。我们还提供了野生型和突变变体的静电计算结果。通过临床、功能和蛋白质信息学的联合多组学方法,我们得出了一个数据融合结果,用于确定该特定基因变体遗传密码中所蕴含的致病性,作为一个平台,它在意义未明的变异分类领域的范围不断扩大。
