Scleroderma is caused by genetic and environmental factors. [ 4 ] [ 5 ] [ 17 ] [ 18 ] Mutations in HLA genes seem to play a crucial role in the pathogenesis of some cases; likewise silica , aromatic and chlorinated solvents, ketones , trichloroethylene , welding fumes, and white spirits exposure seems to contribute to the condition in a small ...
No clear cause for scleroderma and systemic sclerosis has been identified. Genetic predisposition appears to be limited, as genetic concordance is small; still, a familial predisposition for autoimmune disease is often seen. Polymorphisms in COL1A2 and TGF-β1 may influence severity and development of the disease.
Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. [2] The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of the organism's genotype with the environment. [3]
With de novo mutations and division errors, the relationship between the offspring's altered genes and gene inheritance from the parents is technically spurious. [13] These genetic errors can affect the mind as well as the body and can result in schizophrenia, [14] [15] autism, [11] bi-polar disorder, [16] and cognitive [17] disabilities.
An example of how the environment within the womb can affect the health of an offspring is the Dutch hunger winter of 1944–45 and its causal effect on induced transgenerational epigenetic inherited diseases. During the Dutch hunger winter, the offspring exposed to famine conditions during the third trimester of development were smaller than ...
The mechanisms of genetic and ecological inheritance are also different; whereas genetic inheritance depends on reproduction (e.g., sexual and asexual) where genes are transmitted in one direction from parent to offspring in the same species, the modified environment and its selective pressures caused by ecological inheritance can be handed ...
Complex traits are phenotypes that are controlled by two or more genes and do not follow Mendel's Law of Dominance. They may have a range of expression which is typically continuous. Both environmental and genetic factors often impact the variation in expression. Human height is a continuous trait meaning that there is a wide range of heights ...
Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.
