Official Title: Molecular Studies on Hereditary Haemorrhagic Telangiectasia Families With Pulmonary Arteriovenous Malformations
Brief Summary: Hereditary haemorrhagic telangiectasia is a disease inherited as an autosomal dominant disease. Analysing DNA from affected and unaffected family members allows us to identify the location of disease genes by linkage analysis. Sequencing genes in the interval identified by linkage analysis allows us to identify which precise gene is mutated. Further functional studies can then determine why the mutations in that gene cause the disease.
