Any isolated Klippel-Feil syndrome in which the cause of the disease is a mutation in the MEOX1 gene.
Features include: Cleft palate, Sideways curvature of the spine (scoliosis), Low posterior hairline, and Short neck and 9 more.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Bones and joints | 3 | Sideways curvature of the spine (scoliosis), Fused cervical vertebrae, Cervical C2/C3 vertebral fusion |
MEOX1 encodes mesenchyme homeobox 1 (254 aa). Mesodermal transcription factor that plays a key role in somitogenesis and is specifically required for sclerotome development. Highest expression in Adipose Subcutaneous (54.5 TPM) and Breast Mammary Tissue (34.8 TPM).
Klippel-Feil syndrome 2, autosomal recessive is associated with mutations in the MEOX1 gene on chromosome 17.
MEOX1 is classified as a druggable target (Transcription Factor category) with score 0.0.
Genetic testing for MEOX1 is available. Testing is considered confirmatory for diagnosis.
