About RIPOR2

Cytogenetic location: 6p22.3 Genomic coordinates (GRCh38): 6:24,804,284-25,042,168 (from NCBI)

This gene has 17 transcripts (splice variants), 214 orthologues, 2 paralogues and is associated with 3 phenotypes. Biased expression in lymph node (RPKM 23.2), spleen (RPKM 16.0) and 11 other tissues.

Summary

This gene encodes an atypical inhibitor of the small G protein RhoA. Inhibition of RhoA activity by the encoded protein mediates myoblast fusion and polarization of T cells and neutrophils. The encoded protein is a component of hair cell stereocilia that is essential for hearing. A splice site mutation in this gene results in hearing loss in human patients.
