16p11.2 rearrangements

Saturday 30 October 2010

16p11.2 rearrangements


- developmental delay
- cognitive impairment
- autism spectrum disorder
- behavioral problems (especially attention-deficit hyperactivity disorder)
- seizures
- obesity
- dysmorphic features
- abnormal head size
- language delay
- learning disabilities
- autism
- academic deficits
- behavioral problems
- long cervicothoracic syringomyelia
- long thoracolumbar syringomyelia
- syringomyelia associated with Chiari malformation


- 16p11.2 deletion
- 16p11.2 reciprocal duplication


Genes (or a single gene) within the implicated interval have significant roles in the pathogenesis of syringomyelia.
