Mutations in the CDKL5 gene (also known as STK9) have recently been shown to cause early onset epilepsy and severe mental retardation (ISSX or West syndrome). Patients with CDKL5 mutations sometimes… (More)
All reported mutations in ALAS2, which encodes the rate-regulating enzyme of erythroid heme biosynthesis, cause X-linked sideroblastic anemia. We describe eight families with ALAS2 deletions, either… (More)
Mutations in MECP2 are a cause of Rett syndrome. Recently, a new isoform of MeCP2 was described, which has an alternative N-terminus, transcribed from exon 1. We screened exon 1 and the promoter… (More)
Hereditary coproporphyria (HCP) is the least common of the autosomal dominant acute hepatic porphyrias. It results from mutations in the CPO gene that encodes the mitochondrial enzyme,… (More)
BACKGROUND
Sporadic porphyria cutanea tarda is a skin disease associated with hepatic siderosis. Depletion of iron stores by phlebotomy is curative. The role of haemochromatosis genes in determining… (More)
MECP2 mutations are identifiable in approximately 80% of classic Rett syndrome (RTT), but less frequently in atypical RTT. We recruited 110 patients who fulfilled the diagnostic criteria for Rett… (More)
Variegate porphyria (VP) is a low-penetrance, autosomal dominant disorder characterized clinically by skin lesions and acute neurovisceral attacks that occur separately or together. It results from… (More)
E rythropoietic protoporphyria (EPP; MIM 177000) is an inherited disorder of haem biosynthesis characterised by the onset in early childhood of lifelong acute photosensitivity of sun-exposed skin. It… (More)
Acute intermittent porphyria (AIP) is a low-penetrant autosomal dominant disorder caused by mutations in the hydroxymethylbilane synthase (HMBS) gene. Direct detection of mutations is becoming the… (More)
Erythropoietic protoporphyria (EPP) is a syndrome in which accumulation of protoporphyrin IX in erythroid cells, plasma, skin and liver leads to acute photosensitivity and, in about 2% of patients,… (More)
