Organ System | Phenotype Count | Example Features |
|---|---|---|
Bones and joints | 4 | Cervical C6/C7 vertebrae fusion, Cervical C3/C4 vertebral fusion, Thoracic scoliosis |
GDF3 encodes growth differentiation factor 3 (364 aa). Growth factor involved in early embryonic development and adipose-tissue homeostasis. Highest expression in Kidney Medulla (2.6 TPM) and Spleen (1.3 TPM).
Klippel-Feil syndrome 3, autosomal dominant is associated with mutations in the GDF3 gene on chromosome 12.
GDF3 is classified as a druggable target (Druggable Genome, Growth Factor, and Transcription Factor categories) with score 0.0.
Genetic testing for GDF3 is available. Testing is considered confirmatory for diagnosis.
No clinical trials have been registered for Klippel-Feil syndrome 3, autosomal dominant.
1 publication has been identified in PubMed for Klippel-Feil syndrome 3, autosomal dominant. Research spans Case Report / Case Series (100%).
