Polydactyly of the hand is a common congenital deformity characterised by the presence of one or more supernumerary phalanges and occasionally, extra metacarpals (JIAN, JIANSONG, GUOQIANG et al., 2011). It can be radial (pre-axial), ulnar (post-axial) or central (GRAINNE, 2010). Polydactyly can also be classified as polydactyly type A and type B. In type A, the extra digits contain phalanges.

Surgical procedures t hat remove extra digits are already efficient, effective, and produce great results, so new methods of removal are not currently being researched. Scientists are researching, however, exactly what genes. Scientists have known about polydactyly among these people for years, based on images and skeletal remains showing extremities with extra fingers and toes. But past research revealed only hints. Polydactyly Panel. GTR Test ID Help Each Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number.

Polydactyly is an inherited condition in which a person has extra fingers or toes. It is caused by a dominant allele of a gene. This means it can be passed on by just one allele from one parent if. Even though polydactyly and syndactyly sometimes occur together, there are many differences in epidemiological characteristics and risk factors. Some of the recorded differences are probably random, but some seem certain. There is a clear genetic component in the occurrence of some forms of polydactyly, notably postaxial polydactyly and in some families the trait is transferred as autosomal. Pre-axial polydactyly with an additional digit associated with the thumb Polydactyly or polydactylism (from the Greek poly = many + daktylos = finger), also known as hyperdactyly, is a congenital physical anomaly consisting of supernumerary fingers or toes. When each hand or foot has six digits, it is sometimes called sexdactyly, hexadactyly, or hexadactylism. Although the condition is usually not life-threatening or even particularly debilitating, most.

Polydactyly is polyphenic, i.e., one and the same point mutation can account for a variety of phenotypes. This called for a systemic evo-devo perspective. Instead of a purely genetic explanation for the origin of supernumerary digits, the properties of higher organizational levels, such as interactive cell and tissue dynamics as well as environmental influences, needed to be taken into account. In 14.6% of the 5,927 polydactyly cases, polydactyly was not the only congenital anomaly. This proportion of associated anomalies was minimal for postaxial (11.8%), intermediate for preaxial I (20.0%), and maximal for rare polydactyly (54.9%). Duplication of the fifth toe plus syndactyly of fourth and fifth toes, as well as other syndactylies adjacent to the duplicated digit, was the most. Polydactyly is considered to be one of the common congenital hand anomalies. Classification of congenital hand anomalies by Swanson groups similar forms of deficits affected by specific embryological failures. Each type of polydactyly has its separate classification. This case series suggested classification that could include the radial and ulnar variants of polydactyly in one classification. Polydactyly, primarily presenting as an additional pre‐axial or post‐axial digit of autopod, is a highly heterogeneous condition and depicts broad inter‐ and intra‐familial clinical variability. There is a plethora of polydactyly classification methods reported in the medical literature which approach the heterogeneity in polydactyly in various ways.
