Phenotypes associated with the disease Klippel-Feil syndrome 2, autosomal recessive (OMIM:214300):
- Cleft palate (HP:0000175): Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate). Evidence: TAS. (OMIM:214300)
- Scoliosis (HP:0002650): The presence of an abnormal lateral curvature of the spine. Evidence: TAS. (OMIM:214300)
- Low posterior hairline (HP:0002162): Hair on the neck extends more inferiorly than usual. Evidence: TAS. (OMIM:214300)
- Short neck (HP:0000470): Diminished length of the neck. Evidence: TAS. (OMIM:214300)
- Ventricular septal defect (HP:0001629): A hole between the two bottom chambers (ventricles) of the heart. The defect is centered around the most superior aspect of the ventricular septum. Evidence: TAS. (OMIM:214300)
- Sensorineural hearing impairment (HP:0000407): A type of hearing impairment in one or both ears related to an abnormal functionality of the cochlear nerve. Evidence: TAS. (OMIM:214300)
- Fused cervical vertebrae (HP:0002949): A congenital anomaly characterized by a joining (fusion) of two or more cervical vertebral bodies with one another. Evidence: TAS. (OMIM:214300)
- Autosomal recessive inheritance (HP:0000007): A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele). Evidence: TAS. (OMIM:214300)
- Sprengel anomaly (HP:0000912): A congenital skeletal deformity characterized by the elevation of one scapula (thus, one scapula is located superior to the other). Evidence: TAS. (OMIM:214300)
- Conductive hearing impairment (HP:0000405): An abnormality of vibrational conductance of sound to the inner ear leading to impairment of sensory perception of sound. Evidence: TAS. (OMIM:214300)
- Limited neck range of motion (HP:0000466). Evidence: TAS. (OMIM:214300)
- Abnormal pinna morphology (HP:0000377): An abnormality of the pinna, which is also referred to as the auricle or external ear. Evidence: TAS. (OMIM:214300)
- Cleft upper lip (HP:0000204): A gap or groove in the upper lip. This is a congenital defect resulting from nonfusion of tissues of the lip during embryonal development. Evidence: TAS. (OMIM:214300)
- Cervical C2/C3 vertebral fusion (HP:0004602): Fusion of cervical vertebrae at C2 and C3, caused by a failure in the normal segmentation or division of the cervical vertebrae during the early weeks of fetal development, leading to a short neck with a low hairline at the back of the head, and restricted mobility of the upper spine. Evidence: IEA. (OMIM:214300)
