Abstract

Osteogenesis imperfecta (OI) is a genetic disorder causing skeletal fragility, multiple fractures, and other extraskeletal manifestations. Most cases are caused by mutations in or . Recent investigations have discovered several other autosomal recessive genes responsible for OI. Among these genes is , which is involved in post-translational modifications of collagen. To date, more than 40 mutations have been described. One of these mutations is carried by 1.5% of West Africans and 0.4% of African Americans, and is associated with OI Type VIII. We describe the case of a five year old male with a moderate form of OI and compound heterozygous LEPRE1 mutations (c.1080 + 1G > T; c.1646 T > G, p.Met549Arg). He was diagnosed shortly after birth following a skeletal survey demonstrating multiple healing fractures as well as lower extremity deformity suggestive of remote fractures. He was then without a fracture until a calvarial fracture at 18 months of age, a femur fracture at 4 years and seven months and a second femur fracture at 5 years and 4 months. He walked at age 14 months and has been an active boy. Pamidronate infusions began at seven weeks of age and were discontinued at three years of age due to increased bone mineral density and absence of fractures. Type VIII OI typically causes a severe to lethal phenotype presenting at birth with severe osteopenia, congenital fractures and other clinical manifestations. Only a few individuals have survived to childhood. This case description serves to expand the clinical phenotyping of this recessive form of OI into the more moderate spectrum.

摘要

成骨不全症(OI)是一种遗传性疾病,可导致骨骼脆弱、多发性骨折及其他骨骼外表现。大多数病例由 或 基因的突变引起。最近的研究发现了其他几个导致OI的常染色体隐性基因。其中一个基因是 ,它参与胶原蛋白的翻译后修饰。迄今为止,已描述了40多种 基因突变。这些突变之一在1.5%的西非人和0.4%的非裔美国人中存在,并与VIII型OI相关。我们描述了一名5岁男性的病例,他患有中度OI,存在复合杂合性LEPRE1突变(c.1080 + 1G > T;c.1646 T > G,p.Met549Arg)。他出生后不久经骨骼检查被诊断出患有该病,检查显示有多处愈合骨折以及提示陈旧性骨折的下肢畸形。此后直到18个月大时发生颅骨骨折、4岁7个月时发生股骨骨折以及5岁4个月时发生第二次股骨骨折之前,他未再发生骨折。他14个月大时开始走路,一直是个活跃的男孩。帕米膦酸输注在7周龄时开始,由于骨密度增加且未发生骨折,在3岁时停止。VIII型OI通常会导致严重至致命的表型,出生时即表现为严重骨质减少、先天性骨折及其他临床表现。只有少数个体存活至儿童期。本病例描述有助于将这种隐性OI的临床表型扩展到更中度的范围。
