[Prenatal genetic diagnosis of type I autosomal dominant polycystic kidney disease]
Insights
Genetic analysis identified Autosomal Dominant Polycystic Kidney Disease (ADPKD) Type I in a proband. Prenatal diagnosis allowed for termination of two affected pregnancies and the birth of a healthy child from the third.
Area of Science:
- Medical Genetics
- Reproductive Medicine
- Nephrology
Background:
- Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common inherited disorder.
- Genetic analysis is crucial for diagnosing ADPKD and understanding its inheritance patterns.
- Reproductive choices for affected individuals require accurate genetic information.
Purpose of the Study:
- To report a case of Autosomal Dominant Polycystic Kidney Disease (ADPKD) Type I.
- To illustrate the application of molecular genetic analysis in prenatal diagnosis for ADPKD.
- To highlight the role of genetic counseling and antenatal care in managing pregnancies affected by ADPKD.
Main Methods:
- Molecular genetic analysis of the proband to determine ADPKD type.
- Prenatal diagnosis through fetal genetic testing in three pregnancies.
- Genetic counseling provided to the proband regarding test results and implications.
Main Results:
- The proband was diagnosed with Autosomal Dominant Polycystic Kidney Disease (ADPKD) Type I.
- Two fetuses were identified as carriers of the mutant gene and pregnancies were terminated.
- The third fetus was confirmed to be non-carrier, resulting in the birth of a healthy male infant.
Conclusions:
- Molecular genetic analysis is effective for prenatal diagnosis of ADPKD Type I.
- Genetic counseling and antenatal care are essential components in managing ADPKD pregnancies.
- Prenatal diagnosis empowers informed reproductive decisions for families with ADPKD.
Abstract:
Probanda affected with autosomal dominant polycystic kidney disease (ADPKD) had a molecular genetic analysis which indicated the type I. Of the three pregnancies in the probanda, first two had mutant gene carrier fetuses and these pregnancies were terminated. The fetus of the third pregnancy had no mutant gene and this pregnancy ended in the birth of a healthy boy. The principles of genetic counselling and antenatal care are summarised in ADPKD type I.
