Clinodactyly is an autosomal dominant trait that has variable expressiveness and incomplete penetrance. [citation needed] Clinodactyly can be passed through inheritance and presents as either an isolated anomaly or a component manifestation of a genetic syndrome. [2] Many syndromes are associated with clinodactyly, including those listed below.
Pressure on the nerves can cause tingling sensations, numbness, pain, weakness, muscle atrophy and even paralysis of the affected area. In normal individuals, these symptoms disappear quickly, but in sufferers of HNPP even a short period of pressure can cause the symptoms to occur.
It is caused by mutations in the short-stature homeobox gene found in the pseudoautosomal region PAR1 of the X and Y chromosomes, at band Xp22.33 or Yp11.32. [2]SHOX gene deletions have been identified as the major cause of Leri–Weill syndrome.
Primary ciliary dyskinesia (PCD) is a rare, autosomal recessive genetic ciliopathy, that causes defects in the action of cilia lining the upper and lower respiratory tract, sinuses, Eustachian tube, middle ear, fallopian tube, and flagella of sperm cells. The alternative name of "immotile ciliary syndrome" is no longer favored as the cilia do ...
Intellectual disability-spasticity-ectrodactyly syndrome, also known as Jancar syndrome, [1] [2] is a rare autosomal recessive genetic disorder which is characterized by severe intellectual disabilities, hereditary spastic paraplegia, and defects of the distal limbs, such as syndactyly, ectrodactyly, and clinodactyly.
Andersen–Tawil syndrome, also called Andersen syndrome and long QT syndrome 7, is a rare genetic disorder affecting several parts of the body. The three predominant features of Andersen–Tawil syndrome include disturbances of the electrical function of the heart characterised by an abnormality seen on an electrocardiogram (a long QT interval) and a tendency to abnormal heart rhythms ...
Cleidocranial dysostosis (CCD), also called cleidocranial dysplasia, is a birth defect that mostly affects the bones and teeth. [1] The collarbones are typically either poorly developed or absent, which allows the shoulders to be brought close together. [1]
Potassium levels may be low, high, or normal during attacks of ATS. Patients with ATS may also have skeletal abnormalities like scoliosis (curvature of the spine), webbing between the second and third toes or fingers , crooked fingers (clinodactyly), a small jaw (micrognathia) and low-set ears. Patients need to have another form of periodic ...
