Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Osteolysis, distal, with short stature, mental retardation, and characteristic facial
appearance;
Description : Petit and Fryns (1986) described an apparently autosomal recessive form of distal
osteolysis in the son and daughter of unaffected consanguineous parents. The hands
and feet showed severe resorption abnormalities with absence of the distal and middle
phalanges. There was distal muscular hypertrophy, and the skin of the volar part of
the hands was loose without other peculiarities. The osteolysis had begun at an early
age and was rapidly progressive. Changes were most pronounced in the phalanges but
occurred also in the distal ulnar and radial epiphyses. Joint limitation and flexion
contractures developed in the elbows and knees. X-ray changes were evident at age
7 years, and by age 9 almost complete disruption of the distal and middle phalanges
of all fingers and toes had occurred. In addition to the osteolysis the patients were
short in stature, had mild to moderate mental deficiency but satisfactory social adaptation,
and characteristic facies: maxillary hypoplasia, relative exophthalmos, and broad
nasal tip. The surviving sister, aged 57 years, was 146 cm tall. Neurologic examination
was normal. Petit and Fryns (1986) suggested that the same facial features may be
found in patients with multicentric osteolysis or carpal and tarsal osteolysis with
autosomal dominant inheritance. *FIELD* RF 1. Petit, P.; Fryns, J.-P.: Distal osteolysis,
