Meckel-Gruber Syndrome: Defined

Meckel Gruber Syndrome is characterized by congenital (present at birth) deformations of the brain, resulting in mental retardation, cystic growths of the kidneys, and malformations of the hands and feet. The children may also show fibrous growths in the ducts of the liver, bone deformities of the arms and legs, a sloping forehead, cleft palate, cardiac abnormalities, and incomplete development of external and/or internal genitalia. Symptoms vary among each case, however.
These symptoms invariably lead to death primarily due to lung and kidney failure.
While the exact CAUSE of MG-S is unknown, it was not until 1969 that this condition was found to have a genetic link. Only recently have scientists begun to find more genetic components associated with MG-S
Frequency:

Great Britain: 1 in 140,000
Ashkenazi Jews: 1 in 50,000
Finland: 1 in 8500
Massachusetts: 1 in 13,250

    Background: Meckel-Gruber syndrome (MKS) (OMIM 24900) is a lethal, rare autosomal recessive condition mapped to chromosome 17. The triad of occipital encephalocele, large polycystic kidneys, and postaxial polydactyly characterizes MKS. Associated abnormalities include oral clefting, genital anomalies, CNS malformations, and fibrosis of the liver. Pulmonary hypoplasia is the leading cause of death. With the advent of ultrasound, prenatal diagnosis is possible during the second trimester or late first trimester. Pathophysiology: It has been suggested that a failure of mesodermal induction causes MKS. The induction cascades of early morphogenesis involve numerous growth factors, homeo box genes, and paired domain genes. Frequency:
    • Internationally: Worldwide, incidence of MKS varies from 1 in 13,250 to 1 in 140,000 live births. There is a predilection for the Finnish population, in whom the birth incidence is 1 in 9000.
    Mortality/Morbidity: Oligohydramnios resulting from dysplastic kidneys leads to fetal pulmonary hypoplasia. Since the prognosis is grim, with death in utero or shortly after birth, prenatal diagnosis has led to therapeutic abortion of many affected fetuses.

    Keywords: Beckwith-Wiedmann syndrome, adrenal gland, cysts
    Introduction
    Meckel-Gruber syndrome is a rare and lethal autosomal recessive disorder characterized by occipital encephalocele, postaxial polydactyly and bilateral dysplastic cystic kidneys. It can be associated with many other conditions. Antenatal ultrasound examination can establish the correct diagnosis by identifying at least two of the major features described.
    Material and Methods
    A twenty-five-year-old woman with 16 weeks amenorrhea was referred for a second trimester ultrasonogram to detect fetal anomalies. There was history of first-degree consanguinity. The patient had two previous second trimester abortions. Records were not available and the patient stated that both the abortions were due to “abnormal kidneys”.
    Ultrasonography was done using GE logiq 500 PRO equipment, with a 4MHz Curvilinear transducer. The scan revealed bilateral enlarged hyperechoic kidneys (Fig.1,2), occipital encephalocele (Fig.3), six digits in all four limbs (Fig.4) and bilateral clubfeet. Though there was no oligohydramnios the fetal urinary bladder was not visualised both in the initial scan and in all repeat scans done over a period of two days.

    14. The 'MECKEL-GRUBER SYNDROME FOUNDATION'
    The meckelgruber syndrome Foundation. IN THE BEGINNING .. There were many children who suffered due to the devastating disorder meckel-gruber syndrome.

    The Meckel-Gruber Syndrome Foundation
    9/10/01 UPDATE: The DONATION PAGES are now working correctly. Thank you for your patience and understanding. IN THE BEGINNING.....
    There were many children... who suffered due to the devastating disorder: Meckel-Gruber Syndrome
    These parents suffered through a grueling, soul-ripping, devastating and heartbreaking descision-making process during pregnancy and had little comfort because very little is known, or been MADE known TO them, about this terrible disorder.
    This disorder is still prevalent today, and continues it's wave of devastation throughout families around the world. However 'little-known', it's consequences are still far reaching and deep-impacting.
    The Meckel-Gruber Foundation was created to help expand the knowledge or MG-S, provide research funding for MG-S, and down the line once it's firmly established: provide scholarships for medical students, fund support programs for families living with a surviving MG-S child as well as those who have suffered a loss or losses due to MG-S, and other MG-S related programs. HOPEFULLY, the foundation will bring this all-but-unknown disorder up to par (or at least closer than it is at present) with research being done on more well known disorders....such as Multiple Sclerosis or SIDS to name a couple.
    The MG-S Foundation is only in the beginning stages because we need funding to get it going. While it is

    A bit of warning for other searches on the internet. I had the unfortunate experience of coming upon a site that had information on Meckel-Gruber Syndrome, BUT, it was a site with autopsy pictures (I don't have the site listed below). The site didn't just contain information on MGS, it contained many other autopsies on infants with complications. Please be careful when searching the internet. :)

      1. Background
      • the Neuronal Migration Disorders represent a group of disorders where metabolic, chromosomal, hypoxic-ischemic, and/or toxic environmental factors result in a process where there is a general or topical loss of control over neuronal migration after closing of the neural tube and formation of the telencephalic vesicles
      • clinical variability is due to the various etiologies, sites affected, and gestational age at the time of the insult
