Babies with a genetic variant in the mitochondrial MT‑RNR1 gene (m.1555A>G) are at an increased risk of profound bilateral deafness17 Aug 2023 14:19
"Babies with a genetic variant in the mitochondrial MT‑RNR1 gene (m.1555A>G) are at an increased risk of profound bilateral deafness caused by damage to the ear (ototoxicity) if they have treatment with the aminoglycoside family of antibiotics, which includes gentamicin."
' increased risk' means is not a binary situation.
This is interesting in that the negative results in which a baby tests negative for the gene , is prescribed gentamicn yet does go on to lose their hearing is certainly relevant. In other words, the gene is not the only factor. This backs up the side effects listed in wikipedia for antibiotics such as gentacin, they state hearing loss can occur in the elderly and people with wek immune responses (if I recall correctly).
Which means any legal positive of parents suing the NHS , which some trumpian investors have stated, would not be strong at all, as testing negative for the gene only reduces the likelihood of babies losing their hearing after being prescribed gentamicin. And then of course there are the results regarding babies possessing the gene, yet the test results states they don't posses the gene, which of course is an incorrect negative result. This is why testing is so important. And it's incredible to think there are babies who are being tested now who will help save the hearing of other babies in the future.
