The three categories treated for types of spinal cord deficiencies are massive fusion of the cervical spine (Type I), the fusion of 1 or 2 vertebrae (Type II), and the presence of thoracic and lumbar spine anomalies in association with type I or type II Klippel–Feil syndrome (Type III).

It is a congenital disorder in which the fetal development of the lower spine—the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births. [2] Some babies are born with very small differences compared to typical development, and others have significant changes.
Hemivertebrae are wedge-shaped vertebrae and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. [5] The most common location is the midthoracic vertebrae, especially the eighth (T8). [6]
[1] [3] [4] They may be born with congenital vertebral anomalies; parts of the spine may be fused and fail to segment. [4] There may also be extra vertebrae in the lower back. [5] [7] Some of those affected have been reported to have premature fusion of the skull bones (craniosynostosis), particularly those across the midline and at the front ...
There are three common anomalies predominately observed in 13q deletion syndrome: congenital heart disease, anorectal/genitourinary, and gastrointestinal tract malformations. These are all part of the VACTERL associations which is a disorder that is characterized by vertebral anomalies, anal atresia, cardiac defect, tracheoesphageal fistula ...
C - Cardiovascular anomalies; T - Tracheoesophageal fistula; E - Esophageal atresia; R - Renal (Kidney) and/or radial anomalies; L - Limb defects; Although it was not conclusive whether VACTERL should be defined by at least two or three component defects, [4] it is typically defined by the presence of at least three of the above congenital ...
WAGR syndrome (also known as WAGR complex, Wilms tumour-aniridia syndrome, aniridia-Wilms tumour syndrome) is a rare genetic syndrome in which affected children are predisposed to develop Wilms' tumour (a tumour of the kidneys), aniridia (absence of the coloured part of the eye, the iris), genitourinary anomalies, and mental retardation.

Barakat syndrome is a rare disease characterized by hypoparathyroidism, sensorineural deafness and renal disease, and hence also known as HDR syndrome. It is an autosomal dominant condition with incomplete penetrance and variable expressivity [ 2 ] that was first described by Amin J. Barakat et al. in 1977.
