Abstract

Progeria is an ultra-rare (prevalence 1 in 20 million), fatal, pediatric autosomal dominant premature aging disease caused by a mutation in the gene. This mutation results in accumulation of a high level of an aberrant form of the nuclear membrane protein, Lamin A. This aberrant protein, termed progerin, accumulates in many tissues and is responsible for the diverse array of disease phenotypes. Children die predominantly from premature atherosclerotic cardiovascular disease. The Progeria Research Foundation's 10 International Scientific Workshop took place via webinar on November 2 and 3, 2020. Participants from 30 countries joined in this new, virtual meeting format. Patient family presentations led the program, followed by updates on Progeria's first-ever application for FDA drug approval as well as initial results from the only current Progeria clinical trial. This was followed by presentations of unpublished preclinical data on drugs in development targeting the disease-causing DNA mutation, the aberrant mRNA, progerin protein, and its downstream effector proteins. Tying bench to bedside, clinicians presented new discoveries on the natural history of disease to inform future clinical trial development and new Progeria aortic valve replacement procedures. The program engaged the Progeria research community as a single unit with a common goal - to treat and cure children with Progeria worldwide.

摘要

早衰症是一种极为罕见的(发病率为 2000 万分之一)、致命的、儿科常染色体显性过早衰老疾病,由 基因突变引起。这种突变导致高水平的核膜蛋白异常形式的积累,即核纤层蛋白 A。这种异常蛋白,称为早衰蛋白,在许多组织中积累,并导致各种疾病表型。儿童主要死于早发性动脉粥样硬化性心血管疾病。早衰症研究基金会于 2020 年 11 月 2 日和 3 日通过网络研讨会举行了第 10 届国际科学研讨会。来自 30 个国家的参与者参加了这种新的虚拟会议模式。患者家属的演讲引领了整个计划,随后更新了早衰症首次向 FDA 申请药物批准的情况,以及唯一目前正在进行的早衰症临床试验的初步结果。接下来是正在开发的针对疾病相关 DNA 突变、异常 mRNA、早衰蛋白及其下游效应蛋白的药物的未发表的临床前数据。从理论研究到临床应用,临床医生介绍了关于疾病自然史的新发现,为未来的临床试验开发和新的早衰症主动脉瓣置换手术提供了信息。该计划将早衰症研究界作为一个单一的整体,共同目标是治疗和治愈全世界的早衰症儿童。
