Abstract:
The triphalangeal thumb (TPT) is a rare malformation in which the thumb is presented as a long digit of three phalanges. We describe two brothers showing TPT and psychomotor retardation, especially in language. Difficulties in language development were also observed in children with TPT in another study. The coexistence of TPT and psychomotor retardation in those patients and in the two patients described here suggests that TPT and psychomotor retardation could be part of a syndromic association not described previously.
