Incomplete penetrance and phenotypic variability characterize Gdf6-attributable oculo-skeletal phenotypes.
Proteins of the bone morphogenetic protein (BMP) family are known to have a role in ocular and skeletal development; however, because of their widespread expression and functional redundancy, less progress has been made identifying the roles of individual BMPs in human disease. We identified seven heterozygous mutations in growth differentiation factor 6 (GDF6), a member of the BMP family, in p...
متن کاملIncomplete penetrance of MHC
We propose an approach to understanding incomplete penetrance of disease susceptibility genes as a method of studying the underlying mechanisms of polygenic diseases. Incomplete penetrance is the failure of genetically susceptible individuals to exhibit a trait. We define as baseline penetrance that which occurs in genetically identical (monozygotic) twins of an index subject with a major histo...
متن کاملPhenotypic variability and incomplete penetrance of spontaneous fractures in an inbred strain of transgenic mice expressing a mutated collagen gene (COL1A1).
Phenotype variability and incomplete penetrance are frequently observed in human monogenic diseases such as osteogenesis imperfecta. Here an inbred strain of transgenic mice expressing an internally deleted gene for the pro alpha 1(I) chain of type I procollagen (COL1A1) was bred to wild type mice of the same strain so that the inheritance of a fracture phenotype could be examined in a homogene...
متن کاملIncomplete penetrance: The role of stochasticity in developmental cell colonization.
Cell colonization during embryonic development involves cells migrating and proliferating over growing tissues. Unsuccessful colonization, resulting from genetic causes, can result in various birth defects. However not all individuals with the same mutation show the disease. This is termed incomplete penetrance, and it even extends to discordancy in monozygotic (identical) twins. A one-dimensio...
متن کاملMolecular-Genetic Mapping of Zebrafish Mutants with Variable Phenotypic Penetrance
Forward genetic screens in vertebrates are powerful tools to generate models relevant to human diseases, including neuropsychiatric disorders. Variability in phenotypic penetrance and expressivity is common in these disorders and behavioral mutant models, making their molecular-genetic mapping a formidable task. Using a 'phenotyping by segregation' strategy, we molecularly map the hypersensitiv...
