Psoriasis, bulbar involvement, and diarrhea in late myoclonic epilepsy with ragged-red fibers-syndrome due to the m.8344A > G tRNA (Lys) mutation

Myoclonic epilepsy and ragged red fibers (MERRF) syndrome: selective vulnerability of CNS neurons does not correlate with the level of mitochondrial tRNAlys mutation in individual neuronal isolates.

Selective vulnerability of subpopulations of neurons is a striking feature of neurodegeneration. Mitochondrially transmitted diseases are no exception. In this study CNS tissues from a patient with myoclonus epilepsy and ragged red fibers (MERRF) syndrome, which results from an A to G transition of nucleotide (nt) 8344 in the mitochondrial tRNALys gene, were examined for the proportion of mutan...

Mutation Causes Merrf Syndrome Phe a Novel Mitochondrial Trna

A woman with typical features of myoclonic epilepsy with ragged red fibers (MERRF) had a novel heteroplasmic mutation (G611A) in the mitochondrial DNA tRNA phenylalanine gene. The mutation was heteroplasmic (91%) in muscle but undetectable in accessible tissues from the patient and her maternal relatives. Single-fiber PCR analysis showed that the proportion of mutant genomes was higher in cytoc...

Insensitivity to pain due to Genetic Mutation

Pain is neuroanatomically, psychologically and neurophysiologically complicated and its first function is protecting all alive creature body. This issue is so questionable and interesting that people who don’t feel pain how face this sensation and what problems threaten them. So many researchers by using 73 references, articles from electronical and library references have done a clinical...

Merrf Syndrome and Refractory Status Epilepticus

MERRF syndrome (or Myoclonic Epilepsy with Ragged Red Fibers) is a mitochondrial disease maternally-inherited. In this progressive disorder, status epilepticus is common and highly resistant to treatment including generalized anesthesia. We report two cases with Merrf syndrome (sister and brother), presented with status epilepticus refractory even to Thiopental, Propofol and Midazolam. In the s...
