carrier detection of duchenne muscular dystrophy (dmd) in females using real time pcr
نویسندگان
چکیده
introduction: duchene/ becker (dmd/bmd) muscular dystrophy is the most frequent neuromuscular disease in children which is inherited as an x-linked recessive trait. the disease is caused by partial deletion in dystrophin gene. we developed a rapid and robust method for direct identification of female carriers of deletions and duplications in the dystrophin gene, in order to prevent the affected newborn males to be born. materials and methods: qantitative real-time pcr assay for deletion/duplication within two major hot spots in dystrophin gene (exon 6 and 47) was developed and an x-linked gene was considered as a normalizer (i.e., a fragment of human coagulation factor ix gene).the quantitative real-time pcr test was conducted using comparative threshold method (δδct). results: the results showed 2-δδct of 1.09±0.21 for normal individuals and 0.51±0.1 for carrier samples. carrier status was accurately attributed in 100% of cases. conclusion: this method is simple, rapid, reliable and cost-effective. it may be applied for direct determination of deletion/duplication in potential dmd/bmd carriers and may easily be adapted for other genetic conditions involving deletions and duplications.

Sir, I read with interest the paper by Mollica et al.1 and should like to add the results of our prospective study for comparison with other Mediterranean countries on 37 HBsAg mothers who were found among 1002 pregnant women attending a maternity hospital. Although 3.7% of the mothers were positive for HBsAg, only in 0. 1 % of cord blood specimens was HBsAg demonstrable by counter electrophore...
متن کاملCarrier detection in Duchenne muscular dystrophy using molecular methods
BACKGROUND & OBJECTIVES Duchenne and Becker muscular dystrophies are X-linked allelic disorders which are caused by mutations in the DMD gene. Carrier analysis in DMD is complicated due to the heterozygous nature of the X chromosome. Several techniques have been tried for carrier analysis in families where the mutation is identified including quantitative multiplex PCR (qmPCR), Southern blot, a...

DMD certainly has a remarkable position amongst all hereditary muscle disorders. Noteworthy is its relatively high incidence as a " rare disease " , its X-chromosomal mode of inheritance, the high frequency of new mutations , as well as its relatively rapid and fatal course. For a century the disorder was considered to be untreatable. Only 40 years ago the patients' " natural " age at death was...

Background Duchenne Muscular Dystrophy (DMD) is a deadly X-linked recessive disorder. This genetic disorder affects 1 among 3,500-5,000 males in the world. The majority of the patients are male, due to the type of inheritance. It affects most of the skeletal, the respiratory, and cardiac muscles, causing these vital organs to contract and eventually mortality.<br...
