There are several categories, the most important of which is divided into two types of type I and type 2 neurofibromatosis. Here, we aimed to identify th...

hemophilia b is factor ix deficiency and is inherited as x-linked recessive disorder. the subject of carrier detection in hemophilias has received new impetus in the last several years. analysis of factor ix gene polymorphisms is considered the best approach for prenatal diagnosis and hemophilia b carrier detection, if the identification of the gene mutation is possible. allele frequencies of t...

fibrodysplasia ossificans progressiva (fop, mim 135100) is a rare genetic disease that is often inherited sporadically in an autosomal dominant pattern. the disease manifests in early life with malformed great toes and, its episodic and progressive bone formation in skeletal muscle after trauma is led to extra-articular ankylosis. in this study, a 17 year-old affected girl born to a father with...

objective(s): it has been reported that the mutation of the pre-core (pc) and basal-core promoter (bcp) may play an important role in the development of hbv-related hepatocellular carcinoma (hcc). in this study the pc and bcp mutations were investigated in chronic hbv patients. materials and methods:in this study, 120 chronic hbv patients from golestan, northeast of iran who were not vaccinated...
