We report of an Iranian family with history of a rare haemoglobin variant, Haemoglobin J associated with alpha thalassemia, discovered while performing premarital thalassemia screening. In the present study we report the first case of haemoglobin J-Toronto [alpha 5 (A3) Ala > Asp] on -globin gene, found in a 16-year-old female from Mazandaran Province, North of Iran. Further investigation chara...

Objective(s): Non-syndromic sensorineural hearing loss (NSHL) is a common disorder affecting approximately 1 in 500 newborns. This type of hearing loss is extremely heterogeneous and includes over 100 loci. Mutations in the GJB2 gene have been implicated in about half of autosomal recessive NSHL (ARNSHL) cases, making this the most common cause of ARNSHL. For the latter form of deafness, most f...

BACKGROUND Cutaneous leishmaniasis is still a health problem in many rural and urban regions of Iran and drug resistance has emerged as a major impediment in the treatment of leishmaniasis. This study aims to determine the drug resistance gene in cutaneous leishmaniasis by PCR in some endemic areas of Iran. METHODS Ninety seven samples were collected from ulcers of leishmaniasis patients from...

I would like to thank Dr Sendi and Mohseni for their interest in our study.In this letter the authors have summarized the contributory effects of hereditary hemochromatosis (HH) in liver diseases in different populations (1). I completely agree with them concerning the underlying causes of cryptogenic cirrhosis which in countries such as Iran is most commonly nonalcoholic steatohepatitis (NASH)...

Anophthalmia or microphthalmia (A/M) is a rare group of congenital/developmental ocular malformations, characterized by absent or small eye within the orbit affecting one or both eyes. It  has complex etiology with chromosomal, monogenic with high heterogeneity, and environmental causes. We performed genome SNP-array analysis followed by autozygosity mapping and sequencing in the members o...

Wilson disease is a metabolic disorder with an autosomal recessive genetic pattern and occurs in 1-4 of every 100000 individuals. Inactivation of the ATP7B gene leads to accumulation of the toxic copper to liver and brain causing hepatic and neurological complication. Therefore, most patients suffer from chronic hepatic inflammation and central nervous system disorder. Nowadays, up to 500 mutat...
