Scoliosis has historically been categorized into congenital, neuromuscular, and idiopathic forms, and related curves include kyphosis, kypho- scoliosis,andlordosis.Patientsaffectedbyscoliosisareconcernedaboutprognosis, associated health conditions, and recurrence risks. Developmental genetic stud- ies of the spine and linkage and family-based association studies have led to recent advances in understanding the genetic etiology of idiopathic and congeni- talscoliosis.Advancesingenotypingandsequencingtechnologypromisetofurther increaseourunderstandingoftheheterogeneousgroupofdisordersinvolvingspinal curvatures. The inspiration for this volume was derived from the invited session, StraighteningOuttheCurves:UnderstandingtheGeneticsBasisofIdiopathicand CongenitalScoliosisorganizedatthe2008AmericanCollegeofMedicalGenetics, Annual Clinical Genetics Meeting in Phoenix, AZ, USA. The goals of that ses- sion were to bring leading researchers of both congenital and idiopathic scoliosis to present the current state of research and to compare potential shared develop- mentalandgeneticmechanisms.Followinguponthediscussionsfromthissession, thisvolumepresentstherecentadvancesinstudiesofearlyspinaldevelopmentand howdisruptionsinembryonicsegmentationcanleadtocongenitalvertebraldefects.
