The 3 types of Usher Syndrome. Zoey has 2C. We’ve been praying everyday for more funding, more research, know knowledge towards a cure! 🫶🏼
Science Education Friday: The genes for each USH type
Usher syndrome is caused by changes in different genes, grouped into three types, with at least 10 subtypes. Your specific gene can shape your experience with Usher syndrome, your eligibility for clinical trials, and what treatments researchers are working toward.
Here are the genes currently associated with each subtype:
Type 1: USH1B (MYO7A), USH1C, USH1D (CDH23), USH1F (PCDH15), USH1G
Type 2: USH2A, USH2C (ADGRV1), USH2D (WHRN)
Type 3: USH3A (CLRN1), USH3B (HARS)
Each type affects hearing, vision, and balance in different ways, which is why symptoms can vary from person to person.
A note on the naming: subtype names and gene names don't always match. USH1B, for example, is caused by changes in the MYO7A gene. If you know your subtype but not your gene, or vice versa, the list above can help you connect the two.
Don't know your subtype or gene yet? Genetic testing can help, and we can help you figure out where to start.
