A novel mutation in ferroportin1 is associated with haemochromatosis in a Solomon Islands patient.

Genetics of haemochromatosis.

After identification of the hereditary haemochromatosis gene HFE, and receipt of confirmation that most patients with the condition were homozygous for a single, founder mutation (C282Y), most assumed that C282Y would be a prevalent, highly penetrant mutation in a gene that plays a key part in the regulation of iron absorption and of whole-body iron homoeostasis. With carrier rates of between 1...

Novel mutation in ferroportin1 is associated with autosomal dominant hemochromatosis.

Hemochromatosis is a common disorder characterized by excess iron absorption and accumulation of iron in tissues. Usually hemochromatosis is inherited in an autosomal recessive pattern and is caused by mutations in the HFE gene. Less common non-HFE-related forms of hemochromatosis have been reported and are caused by mutations in the transferrin receptor 2 gene and in a gene localized to chromo...

A Novel Missense Mutation in CLCN1 Gene in a Family with Autosomal Recessive Congenital Myotonia

Congenital recessive myotonia is a rare genetic disorder caused by mutations in CLCN1, which codes for the main skeletal muscle chloride channel ClC-1. More than 120 mutations have been found in this gene. The main feature of this disorder is muscle membrane hyperexcitability. Here, we report a 59-year male patient suffering from congenital myotonia. He had transient generalized myotonia, which...

A Novel Splice Site Mutation in HPS1 Gene is Associated with Hermansky-Pudlak Syndrome-1 (HPS1) in an Iranian Family

A Novel Mutation in Exon 4 of the Low Density Lipoprotein (LDL) Receptor Gene in an Iranian Familial Hypercholesterolemia Patient

Familial hypercholesterolemia (FH) is an autosomal co-dominant disorder of lipid metabolism, caused by mutations in LDL receptor gene. The penetrance of FH is almost 100%, meaning that half of the offspring of affected parents born with disease. The patients are at risk of premature coronary heart disease (CHD). There is no report about the molecular basis of FH in Iran. Identification of mutat...
