Minigene therapy for USH2C
Drs. Erwin van Wijk, Erik de Vriezer, and Ronald Pennings have received a €250,000 grant from CUREUsher and Stichting Ushersyndroom to complete a research study focusing on minigene therapy as a possible treatment for USH2C. Due to the large funding this project is receiving it will guarantee this study will be completed within its timeframe of four years. The USH2C project follows a similar research study, minigene therapy as a possible treatment for USH2A, with the final results expected to be released in early 2020.

Deciphering the function of the orphan aGPCR VLGR1/ADGRV1 - USH2C
Mutations in the very large G protein-coupled receptor 1 (VLGR1/ADGRV1) cause the human Usher syndrome (USH2C). These researchers have identified numerous novel potential binding partners and ligands that could be indicative of its pathways and functions. These findings have led to three research projects involving this protein:
a. VLGR1 signaling at focal adhesions.
b. The role of VLGR1 in the formation of autophagosomes.
c. The function of VLGR1 at mitochondria-ER contact sites (MERCSs or MAMs).
USH2C-Related Science News
Merel Stemerdink, a PhD candidate at Radboudumc in Nijmegen, the Netherlands, shares an overview of Usher syndrome and updates on research initiatives at the Radboud University Medical Center. (Captions available in English and Dutch)
Mutations in the genes CIB2 and ADGRV1 have been described as causative for Usher syndrome subtypes USH1J and USH2C, respectively.
Around 40,000 patients in the world have Usher syndrome type 2C, which typically presents with congenital hearing loss and retinitis pigmentosa (RP) due to mutations on the ADGRV1 gene.
