Approximately 10-15% of fracture patients suffer impaired healing, which is either delayed or even results in non-union. We performed a Systematic Review, aiming to examine the types and frequency of specific genetic abnormalities in patients experiencing bone fracture and to ascertain whether a genetic association exists regarding the tendency for some patients to suffer fracture non-union or postoperative non-union events. GO and KEGG analyses were used to identify the likely function of the genes involved. Furthermore, we evaluated the functional significance of single nucleotide polymorphisms using RegulomeDB and GTEx. Seven eligible studies involving 29 genes and 89 SNPs were analyzed in this review. We found that the polymorphisms in gene NOS2, NOG, BMP4, CYR61, IL1β and FGFR1 apparently predisposed patients to fracture non-union, while the polymorphisms in gene MMP13, BMP6 and FAM5C appeared to provide protection from non-union. Bioinformatics analysis suggested that these genes were enriched in inflammatory pathways, suggesting that inflammation may be a potential factor involved in fracture non-union. Three SNPs (rs17563, rs3753793 and rs2853550) had smaller RegulomeDB scores, indicating significant biological function. In conclusion, we have identified a number of genes and their polymorphisms that might contribute to a genetic susceptibility to fracture non-union. Further studies with larger cohorts will enhance our understanding of fracture non-union and may inform and direct early interventions.

骨折不愈合的遗传决定因素:文献综述。

大约10%至15%的骨折患者的康复能力受损,这会延迟甚至导致不愈合。我们进行了系统评价,旨在检查发生骨折的患者中特定遗传异常的类型和频率,并确定某些患者发生骨折不愈合或术后不愈合事件的趋势是否存在遗传关联。使用GO和KEGG分析来鉴定所涉及基因的可能功能。此外,我们使用RegulomeDB和GTEx评估了单核苷酸多态性的功能重要性。本评价分析了涉及29个基因和89个SNP的7项合格研究。我们发现,基因NOS2,NOG,BMP4,CYR61,IL1β和FGFR1的多态性显然使患者容易发生骨折不愈合,而基因MMP13,BMP6和FAM5C的多态性似乎可以提供保护,防止不愈合。生物信息学分析表明,这些基因在炎症途径中富集,表明炎症可能是骨折不愈合的潜在因素。三个SNP(rs17563,rs3753793和rs2853550)的RegulomeDB得分较小,表明其生物学功能显着。总之,我们已经鉴定出许多基因及其多态性,这些基因及其多态性可能导致骨折不愈合的遗传易感性。对更大队列的进一步研究将增进我们对骨折不愈合的理解,并可能为早期干预提供信息和指导。生物信息学分析表明,这些基因在炎症途径中富集,表明炎症可能是骨折不愈合的潜在因素。三个SNP(rs17563,rs3753793和rs2853550)的RegulomeDB得分较小,表明其生物学功能显着。总之,我们已经鉴定出许多基因及其多态性,这些基因及其多态性可能导致骨折不愈合的遗传易感性。对更大队列的进一步研究将增进我们对骨折不愈合的理解,并可能为早期干预提供信息和指导。生物信息学分析表明,这些基因在炎症途径中富集,表明炎症可能是骨折不愈合的潜在因素。三个SNP(rs17563,rs3753793和rs2853550)的RegulomeDB得分较小,表明其生物学功能显着。总之,我们已经鉴定出许多基因及其多态性,这些基因及其多态性可能导致骨折不愈合的遗传易感性。对更大队列的进一步研究将增进我们对骨折不愈合的理解,并可能为早期干预提供信息和指导。我们已经鉴定出许多基因及其多态性,这些基因和基因多态性可能会导致骨折不愈合的遗传易感性。对更大队列的进一步研究将增进我们对骨折不愈合的理解,并可能为早期干预提供信息和指导。我们已经鉴定了许多基因及其多态性,这些基因及其多态性可能导致骨折不愈合的遗传易感性。对更大队列的进一步研究将增进我们对骨折不愈合的理解,并可能为早期干预提供信息和指导。
