Abstract

We provide the first study of two siblings with a novel autosomal recessive LRP1-related syndrome identified by rapid genome sequencing and overlapping multiple genetic models. The patients presented with respiratory distress, congenital heart defects, hypotonia, dysmorphology, and unique findings, including corneal clouding and ascites. Both siblings had compound heterozygous damaging variants, c.11420G > C (p.Cys3807Ser) and c.12407T > G (p.Val4136Gly) in LRP1, in which segregation analysis helped dismiss additional variants of interest. LRP1 analysis using multiple human/mouse data sets reveals a correlation to patient phenotypes of Peters plus syndrome with additional severe cardiomyopathy and blood vessel development complications linked to neural crest cells.

常染色体隐性lrp1相关综合征，以心肺功能障碍、骨畸形和角膜混浊为特征。

我们提供了一个新的常染色体隐性lrp1相关综合征的两个兄弟姐妹的首次研究，通过快速基因组测序和重叠多重遗传模型确定。患者表现为呼吸窘迫、先天性心脏缺陷、低张力、形态异常和独特的表现，包括角膜混浊和腹水。两个兄弟姐妹都有复合杂合有害变异，LRP1的C . 11420g > C (p.Cys3807Ser)和C . 12407t > G (p.Val4136Gly)，其中分离分析有助于排除其他感兴趣的变异。使用多个人/小鼠数据集进行LRP1分析，揭示了与彼得斯综合征患者表型相关的额外严重心肌病和与神经嵴细胞相关的血管发育并发症。

期刊介绍： Cold Spring Harbor Molecular Case Studies is an open-access, peer-reviewed, international journal in the field of precision medicine. Articles in the journal present genomic and molecular analyses of individuals or cohorts alongside their clinical presentations and phenotypic information. The journal''s purpose is to rapidly share insights into disease development and treatment gained by application of genomics, proteomics, metabolomics, biomarker analysis, and other approaches. The journal covers the fields of cancer, complex diseases, monogenic disorders, neurological conditions, orphan diseases, infectious disease, gene therapy, and pharmacogenomics. It has a rapid peer-review process that is based on technical evaluation of the analyses performed, not the novelty of findings, and offers a swift, clear path to publication. The journal publishes: Research Reports presenting detailed case studies of individuals and small cohorts, Research Articles describing more extensive work using larger cohorts and/or functional analyses, Rapid Communications presenting the discovery of a novel variant and/or novel phenotype associated with a known disease gene, Rapid Cancer Communications presenting the discovery of a novel variant or combination of variants in a cancer type, Variant Discrepancy Resolution describing efforts to resolve differences or update variant interpretations in ClinVar through case-level data sharing, Follow-up Reports linked to previous observations, Plus Review Articles, Editorials, and Position Statements on best practices for research in precision medicine.
