Meckel Syndrome Type 7

Meckel-Gruber Syndrome


Presentation

  • Occipital cephalocele is present in 60% to 80% of fetuses. Maternal serum or amniotic fluid fetoprotein level may be normal, as a membrane may cover the cephalocele. Post-axial polydactyly is present in 55% to 75%.[ijri.org]

  • MKS has a variable clinical presentation and affected individuals may not present with all these symptoms.[invitae.com]
  • Herein we describe two cases of MKS presenting as classical triad.[npplweb.com]

Treatment

  • The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment.[orpha.net]
  • It proposes that future advances in the prevention, diagnosis, and treatment of common diseases will come as a consequence of our accelerating progress in the field of rare diseases.[books.google.com]
  • Live births die within the first hours or days of life. treatment not available Meckel - Gruber Syndrom genes known to date sources Barker AR, Thomas R, Dawe HR.[neocyst.de]

Prognosis

  • The exact pathomechanism remains to be elucidated. progress and prognosis High rates of intrauterine death.[neocyst.de]
  • Because the prognosis is grim, with death occurring in utero or shortly after birth, prenatal diagnosis has led to therapeutic abortion of many affected fetuses. The mortality rate is 100%, with most fetuses surviving only a few days to weeks.[emedicine.medscape.com]
