| A lethal skeletal dysplasia with characteristics of cloverleaf skull anomaly, facial dysmorphism, limb shortness, splenic hypo/aplasia and radiological anomalies including thin tubular bones with flared metaphyses and deficient calvarial mineralization. First described in 1989, less than 30 cases have been reported so far. Etiology is not well known, but some histological findings report growth plate disorganization and adjacent diaphyseal ossification. There is evidence that the disease is caused by heterozygous mutation in the FAM111A gene (615292) on chromosome 11q12. |
