About GTPBP3

Cytogenetic location: 19p13.11 Genomic coordinates (GRCh38): 19:17,334,982-17,342,731 (from NCBI)

This gene has 28 transcripts (splice variants), 184 orthologues, 1 paralogue and is associated with 3 phenotypes. Ubiquitous expression in spleen (RPKM 3.4), skin (RPKM 3.3) and 25 other tissues.

Summary

This locus encodes a GTP-binding protein. The encoded protein is localized to the mitochondria and may play a role in mitochondrial tRNA modification. Polymorphisms at this locus may be associated with severity of aminoglycoside-induced deafness, a disease associated with a mutation in the 12S rRNA. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Sep 2010]
