Spondyloepiphyseal dysplasia (SED) Maroteaux type
is a rare skeletal dysplasia that is characterized by short stature beginning in infancy, short, stubby hands and feet, and genu valgum
(knock knees). In addition to these physical characteristics, individuals with SED Maroteaux type have some common radiographic findings, including platyspondyly (flattened vertebral bodies in the spine), abnormalities of the pelvis and severe brachydactyly (short fingers and toes).
Intelligence is generally normal and there is no clouding of the cornea, which distinguishes SED Maroteaux type from other forms of spondyloepiphyseal dysplasia.
SED Maroteaux type is caused by mutations in the TRPV4
gene and is inherited any an autosomal dominant
