Question: 1 / 480

What condition is associated with cleidocranial dysplasia?

Presence of clavicles

Absence of clavicles

Cleidocranial dysplasia is a genetic disorder characterized by the abnormal development of bones and teeth. One of the hallmark features of this condition is the absence or hypoplasia (underdevelopment) of the clavicles, which can lead to an increased range of motion in the shoulders since the collarbones are either absent or significantly underdeveloped. This absence is vital in distinguishing cleidocranial dysplasia from other skeletal dysplasias.

The other options incorrectly suggest scenarios where the clavicles might be present or where there is an ambiguity regarding their presence. However, in individuals with cleidocranial dysplasia, the condition consistently demonstrates the characteristic absence or severe reduction of the clavicles, confirming that the association is uniquely with their absence.
