Cenani-Lenz syndrome in father and daughter

We present a father and daughter with typical clinical and radiological features of Cenani-Lenz syndrome. Cenani-Lenz syndrome has been delineated as a type of complete syndactyly resembling the spoon hand seen in Apert syndrome, with as important additional feature, the fusion of metacarpals and disorganization of the phalanges. Based on the observation of the syndrome in at least two affected siblings born to normal parents and the consanguinity in one family autosomal recessive inheritance was proposed. The findings in the present family could indicate that Cenani-Lenz syndrome may be genetically heterogeneous. Another possible explanation could be that the occurrence in affected siblings born to normal parents could be explained by gonadal mosaicism for an autosomal dominant gene.
