Currarino syndrome

A condition characterized by the combination of: {{}}Partial absence of the sacrum (the lowest portion of spine), Anorectal (anal and rectal) abnormalities, and An abnormal mass in front of the sacrum (due to a meningocoele or teratoma). The malformations in Currarino syndrome are all in tissues that have their embryological origin in the tail bud and may reflect disturbances in its formation during early embryonic life. A mutation (change) in a gene called the HLXB9 homeobox gene has been identified as responsible for autosomal dominant Currarino syndrome, also known as hereditary sacral agenesis.

a complex of congenital anomalies in the anococcygeal region; it consists of partial sacral agenesis; presacral anterior meningocele, teratoma, or cyst; and rectal malformations such as stenosis, ectopia, or imperforation. Gynecologic and renal malformations are also common. In at least some cases it is caused by mutation of the HLXB9 gene (locus: 7q36), a homeobox gene. Called also Currarino triad.
