Defects in joint formation & synostoses

Defects in Joint Formation & Synostoses 

Test Name: Defects in Joint Formation & Synostoses
Test Type: Genetic Testing / Gene Panel

Overview

Defects in joint formation and synostoses are rare congenital skeletal conditions in which abnormal development or fusion of bones leads to restricted joint movement, limb abnormalities, or unusual skeletal architecture. Genetic testing can help identify the underlying molecular cause.

What does this test detect?

This gene panel evaluates genetic variants associated with:

• Abnormal joint development
• Congenital joint contractures
• Bone fusion (synostosis)
• Limb and skeletal abnormalities
• Multiple joint involvement
• Syndromic and non-syndromic skeletal disorders

Who may benefit?

Testing may be considered for individuals with:

• Congenital joint stiffness or restricted movement
• Abnormal fusion between two or more bones
• Limb deformities present from birth
• Multiple congenital skeletal abnormalities
• A suspected inherited skeletal disorder
• A family history of similar skeletal abnormalities

Why is genetic testing useful?

Identifying the genetic cause may help with:

• Establishing or confirming a diagnosis
• Understanding inheritance and recurrence risk
• Guiding clinical management
• Identifying other potentially associated features
• Providing information for family planning and genetic counselling

Sample

Typically EDTA whole blood; sample requirements may vary by laboratory.

Important Note

A genetic test should be interpreted along with clinical findings, family history, imaging and other laboratory investigations. Genetic counselling is recommended before and after testing.
