Syndromes associated with mitochondrial DNA depletion
Mitochondrial dysfunction accounts for a large group of inherited metabolic disorders most of which are due to a dysfunctional mitochondrial respiratory chain (MRC) and, consequently, deficient energy production. MRC function depends on the coordinated expression of both nuclear (nDNA) and mitochondrial (mtDNA) genomes. Thus, mitochondrial diseases can be caused by genetic defects in either the...
متن کاملAdult Mitochondrial DNA Depletion Syndrome with Mild Manifestations
Mitochondrial DNA depletion syndrome (MDS) is usually a severe disorder of infancy or childhood, due to a reduced copy number of mtDNA molecules. MDS with only mild, nonspecific clinical manifestations and onset in adulthood has not been reported. A 47-year-old Caucasian female with short stature and a history of migraine, endometriosis, Crohn's disease, C-cell carcinoma of the thyroid gland, a...
متن کاملMitochondrial depletion syndromes in children and adults.
To highlight differences between early-onset and adult mitochondrial depletion syndromes (MDS) concerning etiology and genetic background, pathogenesis, phenotype, clinical presentation and their outcome. MDSs most frequently occur in neonates, infants, or juveniles and more rarely in adolescents or adults. Mutated genes phenotypically presenting with adult-onset MDS include POLG1, TK2, TyMP, R...
متن کاملCoenzyme Q₁₀ deficiency in mitochondrial DNA depletion syndromes.
We evaluated coenzyme Q₁₀ (CoQ) levels in patients studied under suspicion of mitochondrial DNA depletion syndromes (MDS) (n=39). CoQ levels were quantified by HPLC, and the percentage of mtDNA depletion by quantitative real-time PCR. A high percentage of MDS patients presented with CoQ deficiency as compared to other mitochondrial patients (Mann-Whitney-U test: p=0.001). Our findings suggest t...
متن کاملMyeloproliferative syndromes: diagnosis and therapeutic options.
Myeloproliferative syndromes (MPS) are clonal proliferation of hematopoietic progenitor cells characterized by proliferation of 1 or a few cell lines such as granulocytic, erythroid, megakaryocytic or mastocytic. These syndromes include: chronic myeloid leukemia, polycythemia vera, essential thrombocythemia, myelofibrosis, chronic eosinophilic leukemia/hypereosinophilic syndrome, chronic neutro...
