Hemochromatosis 5 (HFE5)
Note
The disease is caused by variants affecting the gene represented in this entry. In a Japanese family affected by HFE5, a single point mutation has been detected in the iron-responsive element (IRE) in the 5'-UTR of FTH1 mRNA. This mutation leads to an increased binding affinity for iron regulatory protein and thereby to the efficient suppression of mRNA translation
Description
A disorder of iron metabolism characterized by iron overload. Excess iron is deposited in a variety of organs leading to their failure, and resulting in serious illnesses including cirrhosis, hepatomas, diabetes, cardiomyopathy, arthritis, and hypogonadotropic hypogonadism. Severe effects of the disease usually do not appear until after decades of progressive iron loading.
Neurodegeneration with brain iron accumulation 9 (NBIA9)
Note
The disease is caused by variants affecting the gene represented in this entry
Description
An autosomal dominant neurodegenerative disorder associated with iron accumulation, primarily in the basal ganglia. It is characterized by global developmental delay apparent from infancy, and progressive decline of motor and cognitive skills. Clinical features include delayed walking or inability to walk, spasticity with hyperreflexia, ataxia, dystonia, and poor or absent language.
