Detection of large expansions in myotonic dystrophy type 1 using triplet primed PCR
Myotonic dystrophy type 1 (DM1) is an autosomal dominant neuromuscular disease caused by expansion of a CTG trinucleotide repeat in the DMPK gene. Methodology for genetic testing of DM1 is currently not optimal, in particular for the early-onset patients in pediatric populations where large expanded (CTG)n alleles are usually common. Individuals who are homozygous for a normal allele and indivi...
متن کاملMyotonic dystrophy type 1
Myotonic dystrophy type 1 (DM1) is a distal myopathy and a multisystem disease occurring with an incidence of 1/8000, as a result of a CTG trinucleotide repeat expansion in the serinetreonine-protein kinase (DMPK) coding gene on chromosome 19q13.3. In DM1 patients the length of the CTG expansion ranges from 50 to 4000. Disease severity correlates with repeat length and the phenomenon of genetic...
متن کاملDetection of large expansions in SCA8 using a fluorescent repeat-primed PCR assay.
Spinocerebellar ataxia type 8 (SCA8) is a neurodegenerative disorder characterized by slowly progressive cerebellar ataxia. It is caused by bidirectional expression of (CUG)n expansion in the ATXN80S/ATXN8 gene and (CAG)n expansion transcripts in ATXN8. The diagnosis of SCA8 must be confirmed by the presence of a (CTG)n trinucleotide repeat expansion in the ATXN8OS gene. On the other hand, ther...
متن کاملSimple Repeat-Primed PCR Analysis of the Myotonic Dystrophy Type 1 Gene in a Clinical Diagnostics Environment
Myotonic dystrophy type 1 is an autosomal dominant neuromuscular disorder that is caused by the expansion of a CTG trinucleotide repeat in the DMPK gene. The confirmation of a clinical diagnosis of DM-1 usually involves PCR amplification of the CTG repeat-containing region and subsequent sizing of the amplification products in order to deduce the number of CTG repeats. In the case of repeat hyp...
متن کاملGenotype–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...
