青少年特发性脊柱侧凸(AIS)是一种常见的疾病,有很强的遗传易感性证据。AIS易感性的数量性状基因座(QTL)已经在染色体上被确定。我们使用400个标记位点对7个多重家系进行了全基因组遗传连锁扫描,平均间距为8.6厘摩。我们使用Genehunter Plus生成连锁统计,表示为同质性(HLOD)分数,显性和隐性遗传模型。我们在染色体12p上发现了一个重要的连锁信号,其支持区间从12pter附近延伸,跨越约1000万个碱基或31 cM。在该区域内使用20个额外的标记精细定位揭示了最大HLOD = 3.7在5 cM下的显性遗传模型,和分裂峰最大HLOD = 3.2在8和18 cM下的隐性遗传模型。连锁支持区间包含95个已知基因。我们发现的证据表明,连锁的染色体1,6,7,8和14。这项研究是第一个发现12号染色体上AIS易感基因座的证据。在本研究和其他研究中,对多条染色体上AIS易感性QTL的检测表明,这种情况是遗传异质性的。
Adolescent idiopathic scoliosis (AIS) is a common disorder with strong evidence for genetic predisposition. Quantitative trait loci (QTLs) for AIS susceptibility have been identified on chromosomes. We performed a genome-wide genetic linkage scan in 7 multiplex families using 400 marker loci with a mean spacing of 8.6 centiMorgans (cM). We used Genehunter Plus to generate linkage statistics, expressed as homogeneity (HLOD) scores, under dominant and recessive genetic models. We found a significant linkage signal on chromosome 12p, whose support interval extends from near 12pter, spanning approximately 10 million bases or 31 cM. Fine mapping within the region using 20 additional markers reveals maximum HLOD = 3.7 at 5 cM under a dominant inheritance model, and a split peak maximum HLOD = 3.2 at 8 and 18 cM under a recessive inheritance model. The linkage support interval contains 95 known genes. We found evidence suggestive of linkage on chromosomes 1, 6, 7, 8, and 14. This study is the first to find evidence of an AIS susceptibility locus on chromosome 12. Detection of AIS susceptibility QTLs on multiple chromosomes in this and other studies demonstrate that the condition is genetically heterogeneous.
