Is ectrodactyly genetically inherited?
A large number of human gene defects can cause ectrodactyly. The most common mode of inheritance is autosomal dominant with reduced penetrance, while autosomal recessive and X-linked forms occur more rarely. Ectrodactyly can also be caused by a duplication on 10q24.
Who is most likely to get ectrodactyly?
Ectrodactyly is an autosomal dominant ectodermal dysplasia presenting as bilateral congenital malformed hands and feet [1]. It affects about 1 in 90,000 births with males and females equally as likely to be affected.
What type of genetic disease is ectrodactyly?
The ectrodactyly, ectodermal dysplasia, and clefting (EEC) syndrome is an autosomal dominant disorder characterized by a lobster-claw limb anomaly (ectrodactyly), which may be present in one or more limbs, cleft lip and palate, and ectodermal dysplasia.
What is lobster claw syndrome?
Ectrodactyly (also known as a split hand-split foot malformation, cleft hand or lobster claw hand) is a skeletal anomaly predominantly affecting the hands (although the feet can also be affected). The condition has a highly variable severity.
Can lobster hands be fixed?
Not all children need surgery for a cleft hand, particularly if the condition is not too severe and they have good use of their hand. However, if your child’s hand has significant functional or cosmetic problems, their doctor may recommend surgery. There are many different surgical options to repair a cleft hand.
Are there treatments for ectrodactyly?
Reconstructive surgery may be beneficial for individuals with all defects causing functional disability such as ectrodactyly, syndactyly, cleft lip or palate and other associated facial anomalies (e.g., underdeveloped jaw, malformed ears). Dental surgery and corrective devices may be used to treat misshapen teeth.
What is the life expectancy of someone with ectrodactyly?
Lifespan is normal in nearly all types of ectodermal dysplasia.
What is EEC syndrome?
Ectrodactyly ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by the triad of ectrodactyly (development of anomalies of the structures derived from the embryonic ectodermal layer), ectrodactyly (extremities, hands and feet malformations), and cleft lip and/or palate.
Can you fix ectrodactyly?
How many people have lobster claws?
Also known as “lobster-claw syndrome,” ectrodactyly is the absence of the third digit and the fusing together of the remaining fingers and toes into two claws. It affects one in 90,000 at birth, according to Dr. Judith Ranells, a geneticist and pediatrician at the University of South Florida.
What does Symbrachydactyly mean?
Babies with symbrachydactyly (sim-brak-ih-DAK-tuh-lee) are born with short, often webbed fingers. Some might be missing fingers. Symbrachydactyly usually affects just one hand or foot. Sometimes the forearm is short too.
