Definition

Tibial hemimelia-polysyndactyly-triphalangeal thumb syndrome is a rare, genetic dysostosis syndrome, with marked inter- and intra-familial variation, typically characterized by triphalangeal thumbs, hand and/or foot polysyndactyly and/or absent/hypoplastic tibiae (associated with duplication of fibulae in some cases), although isolated triphalangeal thumbs have also been reported. It is often accompanied with remarkable short stature and additional features may include radio-ulnar synostosis and hand oligodactyly, as well as abnormal carpal and metatarsal bones. [from ORDO]

Clinical features

From HPO
Triphalangeal thumb
MedGen UID:
66029
Concept ID:
C0241397
Congenital Abnormality
A thumb with three phalanges in a single, proximo-distal axis. Thus, this term applies if the thumb has an accessory phalanx, leading to a digit like appearance of the thumb.
Preaxial polydactyly
MedGen UID:
87498
Concept ID:
C0345354
Congenital Abnormality
A form of polydactyly in which the extra digit or digits are localized on the side of the thumb or great toe.
Short tibia
MedGen UID:
338005
Concept ID:
C1850259
Finding
Underdevelopment (reduced size) of the tibia.
Fibular duplication
MedGen UID:
478372
Concept ID:
C3276742
Finding
Duplication of the fibula. This may occur as a part of diplopodia (accessory tarsal or metatarsal bone). Diplopodia with double fibula is an extremely rare condition.
Absent tibia
MedGen UID:
478374
Concept ID:
C3276744
Finding
Absence of the tibia.
