New library article on Nasal Irrigations

One gene. Three types of ectodermal dysplasias. That’s the story of the WNT10A gene.

In our new library article, Dr. Kathy Grange, a geneticist at Washington University and Children’s Hospital in St. Louis, explains more about the WNT10A gene and how it manifests into three different types of ectodermal dysplasias. It is a member of the WNT gene family and is essential for the formation of teeth.

Learn What WNT10A Is and Is Not

Some families have told us they have “WNT10A.” It is a true statement that the affected person has that gene. But, saying WNT10A doesn’t indicate which type of ectodermal dysplasia they have.

It’s important to learn which of the three different types it is in order to understand what symptoms you may experience, how to manage them and the chances for passing the gene from parent to child.

The scenario of one gene for three types is similar to a different group of other ectodermal dysplasias caused by the p63 gene. That one gene is known to cause four different types: ankyloblepharon-ectodermal defects-cleft lip and/or plate (AEC) syndrome, ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome, acro–dermato–ungual–lacrimal–tooth (ADULT) syndrome and limb-mammary syndrome. While those conditions may share similar symptoms, they are distinct disorders. The same is true for the WNT10A types.

The Three Types

Hypohidrotic Ectodermal Dysplasia

One of the types caused by WNT10A is hypohidrotic ectodermal dysplasia (HED). HED is considered one of the most common types of ectodermal dysplasia. WNT10A is one of four different genes that can change and cause HED.

However, the form that most people have and are used to reading about is x-linked recessive ectodermal dysplasia (XLHED), which is caused by a completely different gene than WNT10A.

Odonto-Onycho-Dermal Dysplasia (OODD) Syndrome

The second type is called odonto-onycho-dermal dysplasia (OODD) syndrome. This is a more rare type of ectodermal dysplasia affecting the teeth, hair, skin and sweat glands.

The third type is Schopf-Schulz-Passarge syndrome (SSPS). It’s another rare type of ectodermal dysplasia. Dr. Grange’s article explains its unique symptoms and the risk to develop skin cancers.
