Expanding the clinical phenotypes of MT-ATP6 mutations.
Mitochondrial DNA mutations at MT-ATP6 gene are relatively common in individuals suffering from striatal necrosis syndromes. These patients usually do not show apparent histochemical and/or biochemical signs of oxidative phosphorylation dysfunction. Because of this, MT-ATP6 is not typically analyzed in many other mitochondrial disorders that have not been previously associated to mutations in t...
متن کاملMutation analysis of Chinese sporadic congenital sideroblastic anemia by targeted capture sequencing
BACKGROUND Congenital sideroblastic anemias (CSAs) comprise a group of heterogenous genetic diseases that are caused by the mutation of various genes involved in heme biosynthesis, iron-sulfur cluster biogenesis, or mitochondrial solute transport or metabolism. However, approximately 40% of patients with CSA have not been found to have pathogenic gene mutations. In this study, we systematically...
متن کاملGlycine and Folate Ameliorate Models of Congenital Sideroblastic Anemia.
Sideroblastic anemias are acquired or inherited anemias that result in a decreased ability to synthesize hemoglobin in red blood cells and result in the presence of iron deposits in the mitochondria of red blood cell precursors. A common subtype of congenital sideroblastic anemia is due to autosomal recessive mutations in the SLC25A38 gene. The current treatment for SLC25A38 congenital siderobl...
متن کاملSideroblastic anemia.
When first defined 50 years ago, sideroblastic anemia (SA) was already recognized to occur in heterogeneous settings, including as familial or acquired disease. The spectrum of SA has since become considerably expanded with respect to distinct clinical phenotypes as well as discrete causes. The singular feature that typifies all forms of SA and is required for initial diagnosis is the presence ...
