Camptodactyly is a medical condition that causes one or more digits (fingers or toes) to be permanently bent. It involves fixed flexion deformity of the proximal interphalangeal joints. Camptodactyly can be caused by a genetic disorder. In that case, it is an autosomal dominant trait that is known for its incomplete genetic expressivity. This ...
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.
Clinodactyly is a medical term describing the curvature of a digit (a finger or toe) in the plane of the palm, most commonly the fifth finger (the "little finger") towards the adjacent fourth finger (the "ring finger").
Dysmorphic features can vary from isolated, mild anomalies such as clinodactyly or synophrys to severe congenital anomalies, such as heart defects and holoprosencephaly. In some cases, dysmorphic features are part of a larger clinical picture, sometimes known as a sequence, syndrome or association. [2]
Tel Hashomer camptodactyly syndrome is a rare genetic disorder which is characterized by camptodactyly,( a condition where one or more fingers or toes are permanently bent), facial dysmorphisms, and fingerprint, skeletal and muscular abnormalities. [2] [3] This disorder is thought to be inherited in an autosomal recessive fashion. [4]
The syndrome is associated with microcephaly, arthrogryposis and cleft palate and various craniofacial, respiratory, neurological and limb abnormalities, including bone and joint defects of the upper limbs, adducted thumbs, camptodactyly and talipes equinovarus or calcaneovalgus.
In combination with polydactyly Delta shaped extra phalanx. The triphalangeal thumb has a different appearance than normal thumbs. The appearance can differ widely; the thumb can be a longer thumb, it can be deviated in the radio-ulnar plane (clinodactyly), or thumb strength can be diminished.
Congenital limb deformities are congenital musculoskeletal disorders which primarily affect the upper and lower limbs.. An example is polydactyly, where a foot or hand has more than 5 digits.
