There are about 6000 known genetic disorders; many are fatal or cause severe problems while others may not but may add to problems that are triggered by non-genetic (for example, environmental conditions).
Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.
There's clear research showing that anxiety is influenced by genetics. In fact, experts noticed a family connection for anxiety even before they understood how DNA or genes worked. If you have a close relative with anxiety, your chance of developing it's about 2 to 6 times higher than if you don't.
Around 80% of rare diseases are of genetic origin and, of those, 70% already start in childhood.
In pedigrees of families with multiple affected generations, autosomal recessive single-gene diseases often show a clear pattern in which the disease "skips" one or more generations. Phenylketonuria (PKU) is a prominent example of a single-gene disease with an autosomal recessive inheritance pattern.
Schizophrenia. Schizophrenia is thought to have up to 70-80% genetic heritability.

The nature versus nurture debate remains one of the longest-running discussions among the scientific community.

Around 80% of rare diseases are of genetic origin and, of those, 70% already start in childhood.
Approximately 80% of rare diseases are estimated to have a genetic origin. These rare diseases may suffer from missing heritability [15, 16]. One question worth asking is, how can we explain the missing heritability that might be the cause of the challenges we are facing in rare disease diagnostics?
Personality Traits
For example, if the father is an independent thinker or risk-taker, it's likely his daughter will have some of those same qualities. Other personality traits such as intelligence, empathy, creativity, and leadership skills can also be inherited from the father.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Children with generalized anxiety disorder are 3.5 times more likely to have a mother with generalized anxiety disorder. Children with social anxiety disorder are almost 3 times more likely to have a father with anxiety disorder.
Mental disorders are the result of both genetic and environmental factors. There is no single genetic switch that when flipped causes a mental disorder. Consequently, it is difficult for doctors to determine a person's risk of inheriting a mental disorder or passing on the disorder to their children.
Cystic fibrosis (CF) is the most common, fatal genetic disease in the United States. About 30,000 people in the United States have the disease.
