Three different manifestations of congenital muscular aplasia in a family
Acta Paediatrica Scandinavica
|March 1, 1987
Insights
Congenital muscular aplasia/hypoplasia presents in a mother and her children with varied symptoms. This suggests autosomal dominant inheritance with variable gene expression causes these muscle development conditions.
Area of Science:
- Genetics
- Developmental Biology
- Clinical Medicine
Background:
- Congenital muscular aplasia/hypoplasia are rare conditions affecting muscle development.
- Understanding the genetic basis of these disorders is crucial for diagnosis and management.
Observation:
- A mother presented with aplasia of the left tensor fasciae latae muscle.
- Her two children exhibited different manifestations: aplasia of the left depressor anguli oris muscle and right hemidiaphragm hypoplasia.
Findings:
- The observed conditions in the family indicate autosomal dominant inheritance.
- Variable expression (pleiotropy) of the responsible gene explains the diverse clinical presentations.
Implications:
- This case highlights the importance of considering genetic factors in congenital muscle disorders.
- Recognizing variable expression is key for accurate genetic counseling and family screening.
Abstract:
This report concerns three different manifestations of congenital muscular aplasia/hypoplasia in a mother (aplasia of the left tensor fasciae latae muscle) and her two children (aplasia of the left depressor anguli oris muscle, right hemidiaphragm hypoplasia), indicating autosomal dominant inheritance with variable expression (pleiotropy) as aetiology for the conditions.
