BACKGROUND The ANT1 gene, encoding ADP/ATP translocase 1, was investigated in an adult patient with an autosomal recessive mitochondrial disorder characterised by congenital cataracts, hypertrophic cardiomyopathy, myopathy and lactic acidosis. METHODS AND RESULTS ANT1 sequencing showed that the patient was homozygous for a new nucleotide variation,(More)
OBJECTIVE To investigate whether mutations in the SURF1 gene are a cause of Charcot-Marie-Tooth (CMT) disease. METHODS We describe 2 patients from a consanguineous family with demyelinating autosomal recessive CMT disease (CMT4) associated with the homozygous splice site mutation c.107-2A>G in the SURF1 gene, encoding an assembly factor of the(More)
DGUOK [dG (deoxyguanosine) kinase] is one of the two mitochondrial deoxynucleoside salvage pathway enzymes involved in precursor synthesis for mtDNA (mitochondrial DNA) replication. DGUOK is responsible for the initial rate-limiting phosphorylation of the purine deoxynucleosides, using a nucleoside triphosphate as phosphate donor. Mutations in the DGUOK(More)
The POLG genes were sequenced in two unrelated patients presenting with Alpers syndrome. The novel c.3626_3629dupGATA and the c.3643+2T>C alleles were associated in trans with p.A467T and p.[W748S;E1143G], respectively. POLG transcripts from skin fibroblasts showed complete exon 22 skipping for patient 2, but surprisingly partial exon 22 skipping from the(More)
