Dysmorphism-pectus carinatum-joint laxity syndrome is characterised by joint laxity, pectus carinatum and facial dysmorphism (mild frontal bossing, a beaked nose with a low nasal bridge, malar hypoplasia, chubby cheeks, a striking philtrum and arched upper lips). It has been described in two siblings. The mode of transmission is unknown.

Accentuated, prominent philtral ridges giving rise to an exaggerated groove in the midline between the nasal base and upper vermillion border.
