Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Metaphyseal dysostosis, mental retardation, and conductive deafness;
Description : Rimoin and McAlister (1971) reported 3 brothers, born of consanguineous Sicilian parents,
with an apparently autosomal recessive syndrome of metaphyseal dysplasia, short-limb
dwarfism that was more apparent in the lower limbs, mild mental retardation, and conductive
hearing loss. All 3 had repeated episodes of otitis media in childhood. Two had hyperopia
and strabismus. Hands and feet were short and broad with squared-off nails, and fingers
were noted to be markedly loose-jointed in all 3. The major radiographic changes were
limited to the metaphyses, which were widened and irregular with broad areas of irregular
dense calcification. The ribs were short and widened anteriorly with cupping and irregularity
of the costochondral margins. The iliac wings were narrowed with a flattened pelvic
inlet. The proximal femoral heads were well ossified but the femoral necks were small,
resulting in a varus deformity. The long tubular bones were all markedly shortened.
The distal ulnas were shortened and deformed relative to the radii. The lower limbs
were bowed with the fibula longer than the tibia. Genu varum was present. The carpal
and tarsal bones were small but not greatly deformed. The short tubular bones were
all severely shortened with marked epiphyseal-metaphyseal flaring. The phalanges were
wide. *FIELD* RF 1. Rimoin, D. L.; McAlister, W. H.: Metaphyseal dysostosis, conductive
