Mitochondrial tRNA(Ser(UCN)) 7471delC may be a novel mutation associated with maternally transmitted hypertension.
Title: Mitochondrial tRNA(Ser(UCN)) 7471delC may be a novel mutation associated with maternally transmitted hypertension.
These results demonstrated that the m.7505A>G variant affected both structure and function of tRNA(Ser(UCN)) and consequently altered mitochondrial function. The findings highlighted critical insights into the pathophysiology of maternally inherited deafness, which is manifested by the aberrant tRNA metabolism.
Title: A deafness-associated mitochondrial DNA mutation altered the tRNA(Ser(UCN)) metabolism and mitochondrial function.
The authors results suggest that, in addition to sensorineural HI, the m.7510T>C mutation is associated with a spectrum of mitochondrial diseases including migraine, epilepsy, cognitive impairment, ataxia, and tremor, and with evidence of mitochondrial myopathy .
Title: The m.7510T>C mutation: Hearing impairment and a complex neurologic phenotype.
One of the mitochondrial variants responsible for hearing loss is the m.7511T>C mutation located in the mitochondrially encoded tRNA serine 1 (UCN) gene. This is the first report on central European patients harboring the m.7511T>C mutation which reveals that the m.7511T>C may be important when diagnosing patients with maternally inherited hearing loss.
Title: Application of next‑generation sequencing to identify mitochondrial mutations: Study on m.7511T>C in patients with hearing loss.
Mitochondrial COI/tRNASer(UCN) G7444A mutation is associated with aminoglycoside-induced and non-syndromic hearing impairment.
Title: Mitochondrial COI/tRNASer(UCN) G7444A mutation may be associated with aminoglycoside-induced and non-syndromic hearing impairment.
PCDH15 p.Asp1010Gly variant probably modified the phenotypic expression of the 7511T>C mutation in MT-TS1
Title: Mutation in PCDH15 may modify the phenotypic expression of the 7511T>C mutation in MT-TS1 in a Chinese Han family with maternally inherited nonsyndromic hearing loss.
Fatal neonatal lactic acidosis caused by a novel de novo mitochondrial G7453A tRNA-Serine ((UCN)) mutation.
Title: Fatal neonatal lactic acidosis caused by a novel de novo mitochondrial G7453A tRNA-Serine ((UCN)) mutation.
3 deaf probands presented a novel variant, m.7462C>T, which was absent from the same control sample of 306 individuals. It might be a novel pathogenic mutation.
Title: Role of the mitochondrial mutations, m.827A>G and the novel m.7462C>T, in the origin of hearing loss.
