We describe four affected children belonging to a large, highly inbred Muslim family originating from the North West Frontier Province of Pakistan. All children have a similar pattern of skeletal abnormalities, including aplasia/hypoplasia of the ulnae, hypoplasia of the pelvis, aplasia/hypoplasia of the femora, fibular aplasia, and variable digital abnormalities and absent/dysplastic nails. The phenotype overlaps with the syndromes of Fuhrmann, Al-Awadi, and Raas-Rothschild. The present and previously reported families probably share the same geographic and racial origin, indicating a common genetic basis of the reported skeletal abnormalities in these limb-pelvis aplasia and hypoplasia syndromes. A possibility of a new autosomal recessive syndrome in the present family cannot be excluded. Further delineation and molecular studies are required to clarify the genetic cause and phenotypic variation in Fuhrmann, Al-Awadi, and Raas-Rothschild syndromes.
