Werner mesomelic dysplasia with Hirschsprung disease.
Mesomelic dysplasia type Werner is defined by absence of tibiae and preaxial polysyndactyly of hands and feet. Occasional findings are triphalangeal thumbs, absence of patella(e), and dislocated fibula(e). The molecular basis is unknown and autosomal dominant inheritance with variable expressivity is currently postulated. Hirschsprung disease was reported previously in one case. We report here on a new case of mesomelic dysplasia Werner type associated with Hirschsprung disease and bilateral cryptorchidism. We discuss the overlap with the triphalangeal thumb polysyndactyly syndrome located in chromosome 7q36.
