[The Meckel syndrome (author's transl)]
Abstract:
The Meckel syndrome is caused by an autosomal recessive gene. The three main features are encephalocele, polycystic kidneys and polydactyly. At least two of these should be present to establish the diagnosis. Several minor symptoms are observed in various combinations. The possibility of prenatal diagnosis is explained by a case report: A neural tube defect was diagnosed by ultrasonography and AFP-assessment in amniotic fluid whereas unfortunately the presence of polycystic kidneys was not recognized sonographically. The methods of today are able to detect the polydactyly but failed in this case. One can suggest that the complete prenatal diagnosis of the Meckel syndrome is not essential for clinical management since the presence of one major symptom will lead to legal abortion. The search for Meckel syndrome is important in cases of delivery of a child with multiple malformations, indicating a genetic counseling for each subsequent pregnancy.
Insights
Meckel syndrome, a genetic disorder, presents with encephalocele, polycystic kidneys, and polydactyly. Early detection aids genetic counseling for future pregnancies, even if prenatal diagnosis isn't always complete.
Area of Science:
- Genetics
- Medical Diagnostics
- Prenatal Medicine
Background:
- Meckel syndrome is an autosomal recessive genetic disorder.
- Key features include encephalocele, polycystic kidneys, and polydactyly.
- Diagnosis requires at least two major symptoms.
Observation:
- A case report highlights prenatal diagnosis challenges.
- Neural tube defects and AFP levels were assessed via ultrasonography.
- Polycystic kidneys and polydactyly were not fully detected prenatally.
Findings:
- Complete prenatal diagnosis of Meckel syndrome may not be essential for management.
- Identifying even one major symptom can guide clinical decisions.
- Current methods may miss certain congenital anomalies.
Implications:
- Focus on Meckel syndrome is crucial when infants present with multiple malformations.
- Genetic counseling is vital for subsequent pregnancies.
- Improved prenatal screening for all major features is warranted.
