Syndactyly is a congenital condition in which the fingers or toes are webbed or joined together. The web connections most often go up to the first joint of the finger or toe. Simple syndactyly. Syndactyly can be caused by both genetic and environmental factors. This results in the appearance of "webbed" or "super" digits, depending on the extent of the anomaly. Simple syndactyly is fusion only of soft tissue, while complex syndactyly is when finger bones are conjoined. In most cases, when a child is born with syndactyly, there is nothing a parent could have done to cause or prevent this condition. "Fused hooves are just a trivial expres- sion of a dramatic biochemical abnormali- ty," says Dr. This is when two fingers are fused together. If the fingers are completely fused together, it is considered complete. These cats appear throughout history and various populations exist globally. The webbing may be either: Complete — extending from the base of the finger all the way to the tip; Incomplete — stopping at any point before the tip; Complex syndactyly. Recently, two independent mutations in the bovine LRP4 gene have been reported as the primary cause of syndactyly in the Holstein and Angus cattle breeds. Syndactyly is classified as simple or complex, with complex cases involving bony fusion, while Constriction band (amniotic band) syndrome is another possible cause of syndactyly. It can occur alone or as part of a genetic syndrome. Syndactyly is usually congenital and occurs when the webbing between digits fails to dissolve during early fetal development. This article details the aetiology, diagnosis, and treatment of syndactyly. Bilateral involvement is found in 50% of patients. There are many different symptoms and genetic causes.

May 24, 2016 · Syndactyly is classified according to the extent of digital involvement and the character of the tissue involved. 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. Webbed fingers and toes (syndactyly) is when two or more fingers or toes are fused together with skin. Fur- ther research is needed to determine just what biochemical changes the recessive gene causes, however. Complex syndactyly occurs when underlying bones have joined together. Syndactyly, colloquially known as webbed toes, is an uncommon physical attribute wherein an individual possesses two or more toes that are connected by a stretch of skin. What Causes Syndactyly? The exact cause of the condition is unknown. But sometimes, syndactyly happens as part of a genetic syndrome, such as Down's syndrome.

In this form, the bones of the fingers are fused Mutations in either EVC or EVC2 cause Ellis–van Creveld syndrome (EVC), a condition characterized by decreased Hh signaling and polydactyly as one of the phenotypes. This phenotype is present as soft tissue and/or bony fusions, or further characterized as complete fusions if adjacent digits are fused until the fingertips, else, as incomplete. Syndactyly (SD) is a congenital digital malformation characterized by webbing of the fingers and toes.
