Fluorescent PCR and automated fragment analysis for the clinical application of preimplantation genetic diagnosis of myotonic dystrophy (Steinert's disease).

Genotype–Phenotype Correlations in Iranian Myotonic Dystrophy Type I Patients

Objectives: Myotonic Dystrophy type I (DM1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. DM1 is associated with the expansion and instability of CTG repeat in the 3chr('39') untranslated region of the myotonic dystrophy protein kinase (DMPK) gene located on chromosome 19q13.3. The aim of this study w...

Assessment of Preimplantation Genetic Diagnosis (PGD) for Childhood-onset Spinal Muscular Atrophy (SMA) Using Duplex Fluorescent PCR

Abnormal liver function tests in a patient with myotonic dystrophy type 1.

Myotonic dystrophy type 1, also known as Steinert's disease, is a multisystemic disorder with significant genetic and clinical heterogeneity. Apart from skeletal muscles' myotonia and wasting, a variety of system organs can be affected. We report on a 49 years old female patient with unremarkable medical and family history, who presented with elevated liver enzymes without signs or symptoms of...

O-27: Preimplantation Genetic Diagnosis in Prevention of Genetic Diseases -Diagnostic of Spinal Muscular Atrophy (SMA)

Background: Preimplantation genetic diagnosis - PGD is currently an established procedure allowing genetic research of oocyte or embryo before implantation to the uterus. Spinal muscular atrophy (SMA) is a neurodegenerative disorder, being the second most common lethal autosomal recessive disease in Caucasians, after cystic fibrosis. There are three clinically different types of which type I (W...

The myotonic dystrophies: diagnosis and management.

There are currently two clinically and molecularly defined forms of myotonic dystrophy: (1) myotonic dystrophy type 1 (DM1), also known as 'Steinert's disease'; and (2) myotonic dystrophy type 2 (DM2), also known as proximal myotonic myopathy. DM1 and DM2 are progressive multisystem genetic disorders with several clinical and genetic features in common. DM1 is the most common form of adult onse...
