Arthrogryposis multiplex congenita: etiology, genetics, classification, diagnostic approach, and general aspects

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatrics

Background:

• Arthrogryposis is characterized by multiple congenital joint contractures.
• It can occur in isolation or as part of a syndrome, potentially involving the central nervous system.
• The underlying pathogenesis is linked to fetal akinesia, leading to joint contractures.

Purpose of the Study:

• To provide a comprehensive overview of arthrogryposis.
• To describe the causes, genetic factors, and classification of arthrogryposis.
• To outline an approach for diagnosing arthrogryposis.

Main Methods:

• Literature review of arthrogryposis causes.
• Analysis of genetic aspects related to arthrogryposis.
• Review of classification systems for arthrogryposis.
• Description of diagnostic strategies for arthrogryposis.

Main Results:

• Arthrogryposis encompasses a range of congenital conditions.
• Fetal akinesia is a common factor in its development.
• Various genetic and syndromic associations exist.

Conclusions:

• Arthrogryposis is a complex condition with diverse etiologies.
• Understanding its genetic basis and classification is crucial for diagnosis.
• A systematic diagnostic approach is necessary for affected individuals.
