BackgroundWilson disease is an autosomal recessive disorder of copper transport and is characterized by excessive accumulation of cellular copper in the liver and other tissues because of impaired biliary copper excretion and disturbed incorporation of copper into ceruloplasmin. Hepatic failure and neuronal degeneration are the major symptoms of Wilson disease. Mutations in the ATP7B gene are the major cause of Wilson disease.Case presentationIn this study we have screened one pedigree with several affected members, including a 24-year-old Iranian woman and a 20-year-old Iranian man, who showed psychiatric and neurological symptoms of varying severity, by amplifying the coding regions including exon–intron boundaries with polymerase chain reaction and sequencing. We identified c.1924G>C and c.3809A>G mutations in affected members as compound heterozygote state. These mutations segregated with the disease in the family and they were absent in a cohort of 100 Iranian ethnicity-matched healthy controls.ConclusionsNo homozygote state has been reported for these two variants in public databases. In silico predicting tools consider these two variants to be damaging. So this study introduces the novel combination of c.1924G>C and c.3809A>G variants as a cause for Wilson disease.

We characterize a large Italian family presenting with Marfan syndrome (MFS), where the same NM_000138.4:c.6872‐1G > T splice site mutation in the FBN1 gene was detected in 37 affected individuals with different pathological phenotypes. Further studies on such a large pedigree could identify other genetic factors that influence MFS manifestation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
