Larsen syndrome is a condition that causes abnormal development of the bones. Signs and symptoms may include clubfoot and numerous joint dislocations at birth (affecting the hips, knees and elbows); flexible joints; and a distinctive appearance of the face, hands and feet. Larsen syndrome is inherited in an autosomal dominant manner and is caused by mutations in the FLNB gene.[1][2] Management may include surgeries (especially for hip dislocation), and physiotherapy.[1]
