Craniosynostosis-fibular aplasia syndrome

Craniosynostosis-fibular aplasia syndrome (also known as craniosynostosis with fibular aplasia or Lowry syndrome) is a rare syndrome characterized by bicoronal craniosynostosis, absent fibula, cryptorchidism, and bilateral simian creases.

Signs and symptoms
Features of this condition include:


 * Limbs: fibular aplasia, single transverse palmar crease
 * Genitourinary system: cryptorchidism
 * Musculoskeletal system: craniosynostosis

History
The first (and only) reported cases of this syndrome were two brothers first described in 1972. Both had normal intelligence. A follow-up report was made on one the brothers in 1993 at age 25 with two years of college education.

Causes
This condition is genetic but little is known of its cause. Autosomal recessive inheritance has been suggested.
