Adolescent idiopathic scoliosis (AIS) is the most common form of spinal deformity. It occurs mainly in girls and progresses during pre-pubertal and pubertal growth, which is a crucial period for bone mass acquisition. The cause and molecular mechanisms of AIS are not clear; at present the consensus is that AIS has a multifactor cause, with many genetic factors. During the past 5 years, considerable effort has been devoted to identify a gene or genes that cause a predisposition to AIS. Many loci for this disorder have been mapped to different chromosome regions, but no genes have been clearly identified as being responsible for AIS, and, most importantly, the resulting protein defects remain to be shown. We aimed to identify the gene(s) that could be involved in AIS and to validate their involvement by both genetic and functional analyses. A large multiplex AIS French family was chosen for this study on the basis of clinical and radiological data. Whole genome genotyping of the 20 members of this family led to the mapping of a dominant disease-causing gene to two critical genomic intervals (Edery and colleagues, Introduction
