Types of Genetic Mutations

There are two primary types of genetic mutations that can cause Ehlers Danlos Syndrome. These mutations occur in the genes responsible for producing collagen, a protein that provides strength and elasticity to connective tissues in the body.

The first type of mutation is known as a missense mutation, where a single nucleotide change in the DNA sequence leads to the production of an altered collagen protein. This altered protein may have structural defects or reduced functionality, resulting in weakened connective tissues.

The second type of mutation is called a frameshift mutation, which occurs when there's an insertion or deletion of nucleotides in the DNA sequence. This disrupts the reading frame and alters the production of the collagen protein.

Both types of mutations can lead to the development of Ehlers Danlos Syndrome, although the prevalence rates may vary between the different types. The exact prevalence rates for each mutation type aren't well-established, but research suggests that missense mutations are more common than frameshift mutations in individuals with Ehlers Danlos Syndrome.
