Genotype-phenotype correlation of HbH disease in northern Iraq

Genotype-phenotype correlation for leber congenital amaurosis in Northern Pakistan.

OBJECTIVES To report the genetic basis of Leber congenital amaurosis (LCA) in northern Pakistan and to describe the phenotype. METHODS DNA from 14 families was analyzed using single-nucleotide polymorphism and microsatellite genotyping and direct sequencing to determine the genes and mutations involved. The history and examination findings from 64 affected individuals were analyzed to show ge...

Chromosome Duplication (14q) and The Genotype Phenotype Correlation

TBC1D24 genotype–phenotype correlation

OBJECTIVE To evaluate the phenotypic spectrum associated with mutations in TBC1D24. METHODS We acquired new clinical, EEG, and neuroimaging data of 11 previously unreported and 37 published patients. TBC1D24 mutations, identified through various sequencing methods, can be found online (http://lovd.nl/TBC1D24). RESULTS Forty-eight patients were included (28 men, 20 women, average age 21 year...

Phenotype-genotype correlation in haemoglobin H disease in childhood.

In this study we used restriction endonuclease mapping to characterise the molecular defect responsible for haemoglobin H disease in 14 Sardinian children. The resulting genotypes were then correlated with the respective clinical and haematological phenotypes. We found that patients with the combination of non-deletion alpha(+)-thalassaemia [(alpha alpha)th] and deletion alpha(0)-thalassaemia (...

Genotype-phenotype correlation in vanishing white matter disease.

OBJECTIVE Vanishing white matter (VWM) is an autosomal recessive leukoencephalopathy characterized by slowly progressive ataxia and spasticity with additional stress-provoked episodes of rapid and major deterioration. The disease is caused by mutations in the genes encoding the subunits of eukaryotic initiation factor 2B, which is pivotal in translation of mRNAs into proteins. The disease onset...
