Multiple deletions of mtDNA in two brothers with sideroblastic anemia and mitochondrial myopathy and in their asymptomatic mother.

Abstract:

:Two brothers presented with a clinical picture characterized by sideroblastic anemia, mild pancreatic insufficiency and progressive muscle weakness. The presence of an associated permanent basal lactic acidemia raised the suspicion of a mitochondrial disease. A muscle biopsy performed in both siblings proved the presence of a significant number of ragged-red fibers, and respiratory chain enzymatic determinations demonstrated a reduced activity of complexes I, III and IV. Mitochondrial DNA studies disclosed the presence of multiple deletions both in skeletal muscle and, to a lesser extent, in leukocytes. Similar, but not identical deletions were also present in the leukocytes and muscle from their mother. Deletions were flanked by short direct repeats. We conclude that such patients suffer from a familial form of mitochondrial disease clinically resembling Pearson's syndrome, with a probably autosomal dominant inheritance.

  • A region of human chromosome 9p required for testis development contains two genes related to known sexual regulators.

    abstract::Deletion of the distal short arm of chromosome 9 (9p) has been reported in a number of cases to be associated with gonadal dysgenesis and XY sex reversal, suggesting that this region contains one or more genes required in two copies for normal testis development. Recent studies have greatly narrowed the interval conta...
