Raw research findings for this medication. Mostly single studies, not curated or confirmed robust.
Streptomycin was the first aminoglycoside antibiotic and the first effective medicine against tuberculosis, discovered in 1943. It binds bacterial ribosomes and makes them misread genetic instructions. Given by injection, it is used today mainly for drug-resistant tuberculosis, plague and tularaemia. Damage to hearing and balance is its main risk.
The key gene is MT-RNR1, in the DNA of mitochondria, which is inherited from the mother. Variants such as m.1555A>G (rs267606617) make the mitochondrial ribosome resemble a bacterial one, so aminoglycosides can bind it and cause permanent hearing loss, sometimes after a single dose. CPIC has published a guideline on MT-RNR1 and aminoglycosides, and the US FDA lists the pair. Most consumer DNA chips do not read these mitochondrial positions reliably.
