RESUMO
Osteolysis syndromes are rare hereditary disorders characterized by destruction and resorption of affected bones. The current study adds three new patients from two unrelated consanguineous families with a severe form of inherited osteolysis. Clinical examination, radiological, biochemical, ultrastructural and molecular studies were conducted. Clinical and radiological studies suggested the diagnosis of Torg-Winchester syndrome. The three affected patients were homozygous for novel MMP2 gene mutations which confirmed the diagnosis. Our patients are the first to be reported from Egypt thus, supporting the pan ethnic nature of the disease.

We report a rare combination of anomalies in an Egyptian girl with Kabuki syndrome (KS). The 26-month-old girl had imperforate anus with rectovestibular fistula, diaphragmatic defect, congenital heart defects, cleft palate, lower lip pits, hypopigmentation, seizures, hypogammaglobulinemia A, hyperlaxity of joints and premature breast development. This unique combination of anomalies, proposes to carefully investigate cases with KS patient in an attempt to determine their real frequency and in order to improve clinical management. Further, it raises a question about factors determining the variability in phenotypic expression among cases with KS. To our knowledge, this is the first case of KS to be reported from Egypt.
