Currarino syndrome

Overview
Currarino syndrome is a condition where the sacrum (the fused vertebrae forming the back of the pelvis) is not formed properly, there is a mass in the presacral space in front of sacrum, and there are malformations of the anus or rectum. The condition is an autosomal dominant genetic trait caused by a mutation in the HLXB9 homeobox gene.

Currarino syndrome may cause an anterior meningocele or presacral teratoma, or both.
