Which of the following is NOT an attribute of fibrodysplasia ossificans progressiva (FOP)?

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized primarily by the formation of heterotopic ossification (the abnormal growth of bone in soft tissues) following injury or spontaneously. Among the attributes associated with FOP, its hallmark feature is indeed heterotopic ossification, along with progressive loss of mobility as the condition progresses and muscle and connective tissues gradually transform into bone.

The elongation of molar teeth is not recognized as an attribute of FOP. While patients may experience various dental developments or issues over time, elongation of molar teeth is not a characteristic symptom or feature of this condition. Instead, malformation of the great toes is a noted physical trait in individuals with FOP, often presenting as an abnormality in the shape or orientation of the toes.

Understanding these attributes allows for better identification and management of this complex condition, enabling healthcare professionals to support affected patients effectively by focusing on their unique needs throughout the progression of FOP.
