Presentation
These can be divided into those affecting the eyes, spine and other areas:[2]
- Eyes
- Spine
- Other features
- facial dysmorphism
- facial hypotonia
- low posterior hairline
- short webbed neck
- low set ears
- mitral valve prolapse
- aortic valve malformation
- dilated ureters
- sensineural deafness
Genetics
This syndrome is caused by inactivating mutations in the xylosyltransferase (XYLT2) gene. It is inherited in an autosomal recessive manner.
Diagnosis
History
This syndrome was first described by Schmidt et al in consanginous Iraqi family in 2001.[3]
