Clinical and molecular characterisation of 80 patients with 5p deletion: genotype-phenotype correlation

Clinical and molecular characterisation of 80 patients with 5p deletion: genotype-phenotype correlation.

The majority of deletions of the short arm of chromosome 5 are associated with cri du chat syndrome (CdCS) and patients show phenotypic and cytogenetic variability. To perform a genotype-phenotype correlation, 80 patients from the Italian CdCS Register were analysed. Molecular cytogenetic analysis showed that 62 patients (77.50%) had a 5p terminal deletion characterised by breakpoint intervals ...

Genotype-Phenotype Correlation among patients with Dystrophinopathies

Objective: To correlate the site and size of dystrophin gene deletion with the clinical picture in patients with dystrophinopathies. Design: The dystrophin gene is one of the largest known genes. More than half of the dystrophinopathy cases are associated with intrageneic deletions. The importance of the study arises from the fact that dystrophin cDNA probes provide a direct method of genetic d...

Chromosome Duplication (14q) and The Genotype Phenotype Correlation

Molecular genetics, correlation between genotype and phenotype of 65 Vietnames patients with congenital hyperinsulinism

Hyperinsulinemic hypoglycemia (HH) is a consequence of unregulated insulin secretion by pancreatic b-cells. Congenital HH is caused by mutations in genes involved in regulation of insulin secretion (ABCC8, KCNJ11, GLUD1, CGK, HADH, SLC16A1, HNF4A and UCP2). Severe forms of congenital HH are caused by inactivating mutations in ABCC8 and KCNJ11, which encode the two components of the pancreatic b...

Clinical Characteristics and Genotype-Phenotype Correlation of Korean Patients with Spinal and Bulbar Muscular Atrophy

PURPOSE Spinal and bulbar muscular atrophy (SBMA) is an X-linked motor neuron disease characterized by proximal muscle weakness, muscle atrophy, and fas-ciculation. Although SBMA is not uncommon in Korea, there is only one study reporting clinical characteristics and genotype-phenotype correlation in Korean patients. MATERIALS AND METHODS In this study, age at the onset of symptoms, the score...
