IntroductionPopliteal pterygium syndrome is a congenital malformation that includes orofacial, musculoskeletal and genitourinary anomalies. It is a rare autosomal dominant disorder due to a mutation of the IRF6 gene on 1q32.2.Case presentationA one-month-old Moroccan baby boy was diagnosed with typical features of popliteal pterygium syndrome and carried the c.250C>T; p.Arg84Cys mutation of the IRF6 gene.ConclusionsWe report on the first description of a Moroccan popliteal pterygium syndrome patient. This diagnosis allowed us to provide an appropriate course of management to the patient and offer genetic counseling to his family.
Le syndrome de Silver Russell (SSR) est une maladie génétique rare. Sa prévalence est estimée à 1/100.000. Il s’agit d’une pathologie de l’empreinte parentale, caractérisée par une grande diversité phénotypique. Ses signes cliniques majeurs sont: un retard de croissance intra-utérin sévère, un retard staturo-pondéral post natal, une dysmorphie cranio-faciale particulière et une asymétrie des membres. Nous rapportons dans ce travail les observations de trois patients, qui présentent un retard staturo-pondéral, une dysmorphie faciale caractéristique du SSR et une hemihypertrophie corporelle. Nous discutons à travers ces cas les aspects cliniques et génétiques de ce rare syndrome.
