Buttien-Fryns syndrome

Buttien-Fryns syndrome is a congenital genetic disorder that causes severe oligodactyly and micrognathia. It is caused by a change in the structure of the 10q gene. The condition has been reported in four patients, two of which were siblings.

Cause
Buttien-Fryns syndrome is caused by a duplication or triplication of the 10q24 gene. This gene is also associated with other conditions such as split hand. The condition is inherited in an autosomal recessive manner.
