Summary
This study details an Arab family with multiple pterygium syndrome, where parents are first cousins. Prenatal diagnosis via ultrasonography identified affected siblings, highlighting intrafamilial variability.
Area of Science:
- Medical Genetics
- Clinical Medicine
- Human Genetics
Background:
- Consanguineous marriages, such as between first cousins, are known to increase the risk of autosomal recessive genetic disorders.
- Multiple Pterygium Syndrome (MPS) is a rare, heterogeneous group of genetic disorders characterized by webbing (pterygia) between joints and other congenital anomalies.
Observation:
- A report on an Arab family with consanguineous parents (first cousins) presenting with five affected siblings diagnosed with Multiple Pterygium Syndrome.
- The last pregnancy in the family, resulting in an affected sibling, was successfully diagnosed prenatally using ultrasonography.
Findings:
- The study observed significant intrafamilial variability in the clinical manifestations of Multiple Pterygium Syndrome within the described family.
- Prenatal ultrasonography proved effective in diagnosing affected fetuses, allowing for early identification.
Implications:
- Accurate differentiation between various genetic subtypes of Multiple Pterygium Syndrome is crucial for genetic counseling and management.
- This case underscores the importance of considering genetic counseling and advanced diagnostic tools in families with a history of consanguinity and congenital anomalies.
