What is the role of SRCs in the body?
SRCs play important roles in tissues throughout the body, including the skin. Studies suggest that mutations in the KANK2 gene disrupt the regulation of SRCs, which leads to abnormal gene activity. However, it is unclear how these changes underlie the skin and hair abnormalities in keratoderma with woolly hair type IV.
What are the genes that cause keratoderma?
Mutations in the JUP, DSP, DSC2, and KANK2 genes cause keratoderma with woolly hair types I through IV, respectively. The JUP, DSP, and DSC2 genes provide instructions for making components of specialized cell structures called desmosomes. Desmosomes are located in the membrane surrounding certain cells, including skin and heart muscle cells. Desmosomes help attach cells to one another, which provides strength and stability to tissues. They also play a role in signaling between cells.
What is the difference between type III and type IV?
Type III also has signs and symptoms similar to those of type I, including ARVC, although the hair and skin abnormalities are often milder.

What is PPK in medical terms?
Palmoplantar keratoderma (PPK) is a group of skin conditions characterized by thickening of the skin on the palms of the hands and soles of the feet. PPK can also be a feature of various underlying syndromes. [1] . In rare forms of PPK, organs other than the skin may also be affected.
What causes PPKs to be autosomal dominant?
Inherited PPKs are caused by genetic mutations that result in abnormalities of keratin, a skin protein. Depending on the genetic cause, inheritance can be autosomal dominant or autosomal recessive. [1] [2] Treatment is aimed at softening the thickened skin to make it less noticeable and relieve discomfort. [2]
How many carriers of autosomal recessive disorder have children?

What causes PPK to be inherited?
Inherited forms of PPK are caused by genetic mutations that result in abnormalities of keratin (a skin protein ). These forms of PPK may be present in more than one family member. Mutations in several genes can cause an inherited form of PPK.
What is a registry?
A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with Palmoplantar keratoderma. The type of data collected can vary from registry to registry and is based on the goals and purpose of that registry.
How does autosomal dominant inheritance work?
Autosomal dominant inheritance means that having a mutation in only one copy of the responsible gene in each cell is enough to cause features of the condition. In some cases, an affected person inherits the mutated gene from an affected parent. In other cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. For this reason, it is not uncommon for an autosomal dominant condition to be present in more than one generation in a family.
