Polydactyly also occurs in modern extant reptiles [82] and amphibians. [83] Polydactyly was a non-pathological, reacquired condition in extinct marine reptiles such as ichthyosaurs and hupehsuchians, some of which containing upwards of ten digits within their flippers. [84]
One of the polydactyl cats at the Ernest Hemingway House in Key West, Florida.This particular cat has seven (two extra) toes on each paw. A polydactyl cat is a cat with a congenital physical anomaly called polydactyly (also known as polydactylism or hyperdactyly), which causes the cat to be born with more than the usual number of toes on one or more of its paws.
Polydactyly (from Greek πολυ-poly-'many') is when a limb has more than the usual number of digits. This can be: As a result of congenital abnormality in a normally pentadactyl animal. Polydactyly is very common among domestic cats. For more information, see polydactyly.
Synpolydactyly is a combination of syndactyly and polydactyly. This image shows the hand morphology of an individual with polydactyly. SPD is inherited in an autosomal dominant pattern, meaning that an individual only needs to inherit one copy of the affected gene, also known as an allele, from either parent to potentially develop the condition.
Ectrodactyly, split hand, or cleft hand [1] (from Ancient Greek ἔκτρωμα (ektroma) ' miscarriage ' and δάκτυλος (daktylos) ' finger ') [2] involves the deficiency or absence of one or more central digits of the hand or foot and is also known as split hand/split foot malformation (SHFM). [3]
Polysyndactyly may be classified by the level of duplication. The extra digit may be small and comprise only soft tissue, [7] but usually includes at least one bone, most commonly the distal and middle phalanges. [4] [8] Partial or complete duplication of the proximal phalanx, metacarpal or metatarsal can also occur. [4] [7]
Acrocephalosyndactyly presents in numerous different subtypes, however, considerable overlap in symptoms occurs. Generally, all forms of acrocephalosyndactyly are characterized by atypical craniofacial, hand, and foot characteristics, such as premature closure of the fibrous joints in between certain bones of the skull, [16] [17] fusion of certain fingers or toes, [16] [18] and/or more than ...
Santos–Mateus–Leal syndrome, also known as Hirschsprung's disease-deafness-polydactyly syndrome is a very rare autosomal recessive limb malformation which is characterized by Hirschsprung's disease, feet and hand polydactyly, unilateral renal agenesis, and congenital hearing loss. [2] [3] Only 2 cases have been described in medical ...
