Entrez ID 84705
Gene name GTP binding protein 3, mitochondrial
Gene symbol GTPBP3
Synonyms (NCBI Gene)
COXPD23GTPBG3MSS1MTGP1THDF1
Chromosome 19
Chromosome location 19p13.11
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 diseas
