WNT1基因复合杂合突变致成骨不全症15型一例报告
Osteogenesis imperfecta type 15 caused by compound heterozygous mutations in WNT1 gene:a case report
摘要
Abstract
A 9-year-old girl diagnosed with osteogenesis imperfecta ⅩⅤ was reported,who presented with low back pain,lumbar vertebral compression fracture and low bone mineral density.Genetic testing revealed compound hetero-zygous mutations in the WNT1 gene:c.403G>A(p.Val135Ile)and c.901T>A(p.Tyr301Asn).Neither of the parents had a similar phenotype.According to the genetic testing,the mather had a heterozygous mutation of c.403G>A,and the father had a heterozygous mutation of c.901T>A(p.Tyr301Asn).After bisphosphonate treatment,the proband had no recurrence of fracture and bone mineral density increased(Z-score at L1-L4 increased from-4.9 to-0.8),which was considered as the treament effective.The clinical manifestations and diagnosis and treatment characteristics of osteogenesis imperfecta ⅩⅤ were further summarized through literature review to enrich clinicians'understanding of this rare disease.关键词
