Novel heterozygous missense mutation in the platelet glycoprotein Ib? gene associated with isolated giant platelet disorder

Pseudo-von Willebrand disease: a mutation in the platelet glycoprotein Ib alpha gene associated with a hyperactive surface receptor.

Pseudo (platelet-type)-von Willebrand disease is an autosomal dominant bleeding disorder caused by the hyperfunction of a receptor on the platelet surface. The abnormal receptor, glycoprotein Ib, displays increased affinity for its ligand, von Willebrand factor. Four members (normal mother/affected father/two affected daughters) of a family with pseudo-von Willebrand disease were studied to det...

Platelet Glycoprotein Ib-IX and Malignancy

a novel missense mutation, e1623g, in the human factor viii gene associated with moderate haemophilia a

introduction: haemophilia a is the most common inherited x-linked recessive bleeding disorder. the severity of the resultant bleeding diathesis depends on the fviii levels associated with the mutation. analysis of carrier state can be made indirectly by dna linkage analysis or directly by identifying the mutation that leads to the disease. the aim of this study was to identification of the caus...

A Novel Missense Mutation in CLCN1 Gene in a Family with Autosomal Recessive Congenital Myotonia

Congenital recessive myotonia is a rare genetic disorder caused by mutations in CLCN1, which codes for the main skeletal muscle chloride channel ClC-1. More than 120 mutations have been found in this gene. The main feature of this disorder is muscle membrane hyperexcitability. Here, we report a 59-year male patient suffering from congenital myotonia. He had transient generalized myotonia, which...

A Novel Missense Mutation in the ALDH13 Gene Causes Anophthalmia in Two Unrelated Iranian Consanguineous Families

Anophthalmia or microphthalmia (A/M) is a rare group of congenital/developmental ocular malformations, characterized by absent or small eye within the orbit affecting one or both eyes. It  has complex etiology with chromosomal, monogenic with high heterogeneity, and environmental causes. We performed genome SNP-array analysis followed by autozygosity mapping and sequencing in the members o...
