Disorders associated with multiple vertebral segmentation defects may have additional rib anomalies in form of absence or hypoplastic ribs, fanning of ribs, etc. Spondylocostal dysostosis is genetic disorder with abnormal vertebral segmentation and rib anomalies. Diagnosis is often delayed because of non-familiarity with the characteristic features. There are six genes identified for spondylocostal dysostosis, of which SCDO5 is responsible for autosomal dominant form of the disorder. Retrospective study was conducted in Genetic and Metabolic unit of a tertiary hospital in north India over a period of 9 years. Twenty patients with a clinical diagnosis of congenital scoliosis were identified, and reviewed. Three patients were discussed in an earlier report and 11 subsequent patients, are described in this case series here. The median age at presentation was 34 months. The patients showed hemivertebrae, vertebral fusion, fusion of ribs, fanning of ribs. Hydrocephalus/ventriculomegaly was found in three cases and diastematomyelia was identified in one case. Other associated anomalies included corpus callosal agenesis, club foot and capillary malformation. One parent showed rib/spinal defects in two cases. Further studies are needed to characterise the phenotype and genetic basis of scoliosis in Indian patients.
