What Is Usher Syndrome?
9. Ethnicity
Many hereditary conditions are more frequently occurring in specific groups of people that have an ethnic commonality. Sharing common ancestors can make certain people more predisposed to be carriers and sufferers of some disorders.
Genetic research has found that certain ethnicities have been linked to specific gene mutations that cause Usher. Most cases of Usher are descendants of the Ashkenazi Jewish, French Acadians, and the Finnish. A few other clusters have also been found amongst Argentinians for Spanish descent and amongst Nigerians. Knowing your family’s medical history and heritage can be instrumental in arriving at a quick diagnosis.
