What does complex disease mean?
​Complex Disease = A complex disease is caused by the interaction of multiple genes and environmental factors. Complex diseases are also called multifactorial. Examples of complex diseases include cancer and heart disease.
What is complex genetic disorder?
A person will have a complex disorder if he or she has the right combination of genetic differences and environmental exposures. Sometimes these disorders are caused by differences in more than one gene in combination with or without environmental factors.
Which diseases are complex traits?
Examples of complex traits include disorders such as autism, cardiac disease, cancer, diabetes, Alzheimer’s disease, and asthma. Complex traits are believed to result from gene-gene and gene-environment interactions, genetic heterogeneity, and potentially other yet unknown reasons.
What is a term for a complex condition that causes a predictable set of symptoms?
Factitious disorder is a serious mental health disorder in which a person appears sick or produces physical or mental illness. People with factitious disorder deliberately produce symptoms of an illness for the purpose of receiving care and attention in a medical setting.
Why are many common diseases considered complex traits?
Because multiple genetic and nongenetic factors interact to affect phenotype, these diseases and traits are termed complex genetic traits. For most common diseases and complex traits, the underlying genetic variation remains unknown.
Are all disease genetic?
As we unlock the secrets of the human genome (the complete set of human genes), we are learning that nearly all diseases have a genetic component. Some diseases are caused by mutations that are inherited from the parents and are present in an individual at birth, like sickle cell disease.
What are examples of chromosomal abnormalities?
Examples of chromosomal abnormalities include Down syndrome, Trisomy 18, Trisomy 13, Klinefelter syndrome, XYY syndrome, Turner syndrome and triple X syndrome.
What are complex physical traits?
Complex traits, also known as quantitative traits, are traits that do not behave according to simple Mendelian inheritance laws. Examples of complex traits include height, circadian rhythms, enzyme kinetics, and many diseases including diabetes and Parkinson’s disease.
What makes a disease a ” complex disease “?
Many common diseases are influenced by a combination of multiple genes and environmental factors. These diseases are referred to as complex diseases. Many of the most common diseases run in families and are caused by a combination of genetic, environmental and lifestyle factors. These diseases are called complex diseases.
What are some of the most complex genetic disorders?
Researchers are learning that nearly all conditions and diseases have a genetic component. Some disorders, such as sickle cell disease and cystic fibrosis, are caused by variants (also known as mutations) in single genes. The causes of many other disorders, however, are much more complex.
Which is a complex or multifactorial disorder?
Some disorders, such as sickle cell disease and cystic fibrosis, are caused by variants (also known as mutations) in single genes. The causes of many other disorders, however, are much more complex.
What are the different types of immune complex disease?
The types of glomerular histology within the HIVICK family include membranous, IgA nephropathy, diffuse proliferative glomerulonephritis (SLE-like), and a membranoproliferative pattern. The immune complexes in all these lesions contain HIV antigens, which confirm the dependence of the lesion on active viremia.
