Additional Information:
Description: (OMIM) |
Hypermanganesemia with dystonia, polycythemia, and cirrhosis (HMDPC) is an autosomal recessive metabolic disorder characterized by increased serum manganese, motor neurodegeneration with extrapyramidal features, polycythemia, and hepatic dysfunction, which leads to cirrhosis in some cases. Intellectual function is preserved ... |
Clinical Description OMIM |
Tuschl et al. (2008) reported an Arabic girl with a constellation of clinical features consisting of hypermanganesemia, liver cirrhosis, an extrapyramidal motor disorder, and polycythemia. She was born to healthy first-cousin parents. The pregnancy, delivery, and neonatal period ... |
Molecular genetics OMIM |
By homozygosity mapping followed by candidate gene analysis of 2 consanguineous families with HMDPC, Tuschl et al. (2012) identified a deletion in the SLC30A10 gene (611146.0001) in the family reported by Tuschl et al. (2008). The other family ... |
