Prenatal sonographic findings are reported in six fetuses with the Meckel‐Gruber syndrome to illustrate the variety of sonographic findings associated with this disorder and to emphasize the importance of prenatal sonography in helping to establish the correct diagnosis. All six fetuses demonstrated evidence of renal cystic dysplasia Meckel-Grüber syndrome (MGS) was first described in 1822 by Meckel 1 and thereafter in 1934 by Gruber 2. It is a rare congenital polymalformative syndrome with an autosomal recessive mode of inheritance and the postnatal outcome of affected fetuses is invariably lethal. The first reports included the association of occipital encephalocele,.

Meckel syndrome (MKS), also known as Meckel-Gruber syndrome, is a lethal, recessively inherited disorder with a high degree of genetic and phenotypic heterogeneity. It is relatively rare in outbred populations, but in ethnic groups with a high level of consanguinity and in populations where bottlenecks have enriched for recessive disorders the frequency can be greater than 1:10000 Meckel-Gruber syndrome (MGS) is a rare and lethal ciliopathic disorder, with the incidence ranging between 1 in 13 000-400 000 live births. It is a congenital autosomal recessive condition and carries a 25% risk of recurrence in each pregnancy [1, 2] Obviously, in the same manner as in the first trimester, rigorous investigations should be conducted to detect associated signs. The discovery of kidney lesions should in particular be suggestive of Meckel-Gruber syndrome (Fig. 7.3e, f) (Hartge et al. 2010) While sequencing MKS1 and MKS3 genes in 31 unrelated fetuses presenting a cerebro-reno-digital syndrome, which was diagnosed as Meckel-like because of the absence of at least one of the MKS diagnostic criteria, 13 we identified MKS3 mutations in a family with two siblings (fetuses JS-661 and JS-660). In both cases, pregnancies were terminated at 30 wk gestation (WG) and 28 WG. Prune-belly syndrome is characterized by urologic abnormalities, flaccidity, or dysplasia in abdominal wall musculature, and cryptorchidism (in males). Because of the poorly developed abdominal wall muscles, the infant's abdomen has a wrinkled, prune-like appearance, thus giving origins of the syndrome's name

The molar tooth sign is pathognomonic of this condition. Mutations in the MKS1 gene are a major cause of Meckel-Gruber syndrome (MKS), the most common form of syndromic neural tube defects, frequently resulting in perinatal lethality. We present the phenotype and genotype of a child with severe JS and agenesis of the corpus callosum (ACC) There are variety of renal cystic diseases of the fetus (e.g., multicystic dysplastic kidney, autosomal recessive polycystic kidney, autosomal dominant polycystic kidney, obstructive cystic renal dysplasia, simple renal cyst, medullary cystic disease, and syndromes accompanied with renal cystic diseases) The fetal kidneys should be examined to exclude Meckel-Gruber syndrome (encephalocele, polycystic kidneys, polydactyly) [1]. Walker-Warburg syndrome, which also is associated with encephaloceles, is a lethal complex of the CNS and eyes. The diagnosis is established by the detection of lissencephaly, hydrocephalus, and a cerebellar malformation To define a specific sonographic pattern for the appearance of the kidneys in fetuses affected by Meckel-Grüber syndrome (MGS). Methods. This was a retrospective analysis of 30 cases, collected from five centers, with ultrasound features suggestive of MGS. Only fetuses with a confirmed diagnosis of MGS were finally included

Meckel-Gruber syndrome is an autosomal recessive syndrome that has a triad that consists of occipital encephalocele, large renal cystic dysplasia, and polydactyly. Affected patients may also have hepatic developmental defects, oral clefting, and pulmonary hypoplasia as a result of oligohydramnios The second patient, a boy aged 7 years with severe psychomotor retardation, was found to carry a homozygous canonic splice-site sequence variant in TCTN2.

Emmanuel Agapitos, MD,* and Constantinos Christodoulou, MDt Meckel- Gruber syndrome, also known as dysencephalia splachnocystica, was originally described by Meckel in 1822, later by Gruber, and more recently by Opitz and Howe. More than 50 cases of this severe disorder have been reported.' This syndrome is characterized by microcephaly secondary to cerebral and cerebellar hypoplasia as well. The most common location of congenital cystic lesions of the head and neck is listed in Table 2. On MRI, the lesions can vary in T1 and T2 signal intensities, depending on their proteinaceous content, pure fluid, and/or blood products (Figure 2). The cysts should have thin, smooth walls without enhancing mural nodules COACH syndrome is an autosomal recessive developmental disorder, a subtype of Joubert syndrome and related disorders, characterized by cerebellar vermis hypoplasia, oligophrenia, ataxia, coloboma, and hepatic fibrosis.

Mutations in several BBS genes are also responsible for other ciliopathies, such as Meckel-Gruber syndrome, Joubert syndrome, Senior-Loken syndrome, and Leber congenital amaurosis Dandy-Walker malformation can occur due to: Mendelian conditions: Walker-Warburg syndrome, Mohr syndrome, Meckel-Gruber syndrome. Chromosomal aberrations: several duplications involving 5p, 8p, 8q; trisomy 9, duplication on 17q, Turner syndrome. Environmentally induced malformation syndrome: prenatal exposure to rubella, cytomegalovirus. The mammalian embryo progressively develops three sets of excretory organs, all of which might be termed the embryonic kidney. The pronephros and mesonephros regress in the human but induce the metanephros, the direct precursor of the adult kidney (Figure 25-1).The pronephros, a solid mass of cells along the nephrogenic cord, is located at the cervical level at approximately 3 weeks. Meckel syndrome, also known as Meckel-Gruber syndrome, is inherited as an autosomal recessive disorder. This rare condition is characterized by abnormalities affecting several organ systems of the body. Characteristic findings include protrusion of part of the brain and its surrounding membranes (meninges) through a defect in the back or front.
