MELAS and Kearns–Sayre overlap syndrome due to the mtDNA m. A3243G mutation and large-scale mtDNA deletions
This paper reported an unusual manifestation of a 19-year-old Chinese male patient presented with a complex phenotype of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome and Kearns-Sayre syndrome (KSS). He was admitted to our hospital with the chief complaint of "acute fever, headache and slow reaction for 21 days". He was initially misdiagnosed as "vir...
متن کاملSpinocerebellar ataxia and the A3243G and A8344G mtDNA mutations.
The majority of pedigrees with autosomal dominant cerebellar ataxia (ADCA) harbour a pathological expansion of a trinucleotide repeat at one of five genetic loci: spinocerebellar ataxia (SCA) 1, 2, 3, 6, and 7. Other loci have been associated with ADCA in a limited number of families, but in a significant number of pedigrees the genetic basis remains uncertain. Mitochondrial DNA (mtDNA) defects...
متن کاملAssociation of mtDNA mutation with Autism in Iranian patients
The autism spectrum disorders (ASD) are amongst the most heritable complex disorders. Although there have been many efforts to locate the genes associated with ASD risk, many has been remained to be disclosed about the genetics of ASD. Scrutiny's have only disclosed a small number of de novo and inherited variants significantly associated with susceptibility to ASD. These only comprise a small ...
متن کاملMultiple Consequences of a Single Amino Acid Pathogenic RTK Mutation: The A391E Mutation in FGFR3
The A391E mutation in fibroblast growth factor receptor 3 (FGFR3) is the genetic cause for Crouzon syndrome with Acanthosis Nigricans. Here we investigate the effect of this mutation on FGFR3 activation in HEK 293 T cells over a wide range of fibroblast growth factor 1 concentrations using a physical-chemical approach that deconvolutes the effects of the mutation on dimerization, ligand binding...
متن کاملMELAS: A Multigenerational Impact of the MTTL1 A3243G MELAS Mutation.
BACKGROUND the maternally inherited MTTL1 A3243G mutation in the mitochondrial genome causes MelaS (Mitochondrial encephalopathy lactic acidosis with Stroke-like episodes), a condition that is multisystemic but affects primarily the nervous system. Significant intra-familial variation in phenotype and severity of disease is well recognized. METHODS retrospective and ongoing study of an extend...
