"Type 1" is also known as "Jarcho-Levin syndrome", or "JLS". While clinicians almost unanimously refer to the syndrome as "Jarcho-Levin", reports have variously labelled or referred to the condition as all of the following: Hereditary malformations of the vertebral bodies, hereditary multiple hemivertebrae, syndrome of bizarre vertebral anomalies,<unk>  dysplasia, spondylothoracic dysplasia, costovertebral anomalies, costovertebral dysplasia, spondylothoracic dysplasia, occipito-facial-cervico-thoracic-abdomino-digital dysplasia (deemed "ridiculously long" and "unwarranted" by OMIM), and<unk> . A closely related condition termed "Costovertebral segmentation defect with mesomelia and peculiar facies", or Covesdem syndrome, was first described in 1978 in India.
