Ectrodactyly is an uncommon inborn malformation of the hand where the intermediate digit is missing, and the hand is cleft where the metacarpal of the finger should be. This schism gives the hands the show of lobster claws. Ectrodactyly is too known as Karsch neugebauer syndrome. It has been called lobster-claw syndrome because the hands of those affected can appear claw-like. This rare syndrome has many forms and one of the most common of this forms called Type I is associated with a specific region of human chromosome 7 that contains two homeobox genes, DLX5 and DLX6. These genes are similar to a gene in insects called distal-less that controls limb development. When this gene is defective in the fruit fly the distal part of the insect limb is missing. Ectrodactyly may be present alone, or may be part of a number of birth defects. Hand deformation alone is unlikely to affect health.
Ectrodactyly does get several types, and all of them are hereditary. However, heritage of the circumstance happens seldom. Those who have ectrodactyly or get children with the circumstance are at increased danger for passing it onto subsequent children. In this circumstance, the intermediate finger or intermediate toe is missing. As easily, the two fingers or toes to the right and left of the missing finger are fused jointly. This has frequently led to ectrodactyly being called lobster claw hands, or lobster claw syndrome, because the hand deformity does hold some similarity in show to the claws of a lobster. It often occurs in both the hands and the feet. In olden days, a person diagnosed with ectrodactyly usually ended upwards joining a circus sideshow, and go his deformities to his favour. Geneticists establish the circumstance to happen in both humans and worm populations immediately because of the mutated chromosome.
The diagnosis of ectrodactyly syndrome can be complex because of the overlap of symptoms with other ectodermal dysplasia syndromes. Currently there are several treatments, which can normalize the appearance of the hands, yet they will not function precisely the same way as regularly formed hands. The prognosis for most individuals with ectrodactyly syndrome is very good. Some people with ectrodactyly use prosthetic hands to avoid the rude stares of others. Ectrodactyly is an inherited circumstance which can be treated surgically to better role and show. Early physical and occupational therapy can help those with ectrodactyly adapt, and learn to write, pick things up, and be fully functional. Genetic findings could have great implications in clinical diagnosis and treatment of not only ectrodactyly, but also many other related syndromes.
