Attention Deficit Hyperactivity Disorder

Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood disorders and can continue through adolescence and adulthood. Symptoms include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (over-activity).

Autosomal Dominant

Some forms of ectodermal dysplasia, may be inherited in an autosomal dominant fashion.  Autosomal dominant means you need only one mutation to have the disorder.  Autosomal dominant disorders usually have an affected parent, because the parent carries one mutated copy of the gene which is then passed to the child who has the disorder.  More often in families with a child affected by ectodermal dysplasia, the mutation will be a de novo mutation, meaning it has arisen spontaneously, and the parent does not have it, but the child does.

Autosomal Recessive

Ectodermal dysplasias are also inherited in an autosomal recessive fashion. This means both parents contribute a mutation in the same gene to their child.  The child must have both mutations to have an ectodermal dysplasia. The parents are both carriers of ectodermal dysplasia and are unaffected.  The child may inherit a different mutation from each parent in the same gene (heterozygous).  If the child inherits the same mutation from both parents, it is called homozygous.

Bladder diverticulum
