Disorder may refer to :
Deoxyribonucleic acid (i/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/;DNA) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T, and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).
A genetic disorder is a genetic problem caused by one or more abnormalities in the genome, especially a condition that is present from birth (congenital). Most genetic disorders are quite rare and affect one person in every several thousands or millions.
Genetic disorders may or may not be heritable, i.e., passed down from the parents' genes. In non-heritable genetic disorders, defects may be caused by new mutations or changes to the DNA. In such cases, the defect will only be heritable if it occurs in the germ line. The same disease, such as some forms of cancer, may be caused by an inherited genetic condition in some people, by new mutations in other people, and mainly by environmental causes in still other people. Whether, when and to what extent a person with the genetic defect or abnormality will actually suffer from the disease is almost always affected by the environmental factors and events in the person's development.
Some types of recessive gene disorders confer an advantage in certain environments when only one copy of the gene is present.
Bipolar disorder, also known as bipolar affective disorder or manic depression, is a mental disorder characterized by periods of elevated mood and periods of depression. The elevated mood is significant and is known as mania or hypomania depending on the severity or whether there is psychosis. During mania an individual feels or acts abnormally happy, energetic, or irritable. They often make poorly thought out decisions with little regard to the consequences. The need for sleep is usually reduced. During periods of depression there may be crying, poor eye contact with others, and a negative outlook on life. The risk of suicide among those with the disorder is high at greater than 6% over 20 years, while self harm occurs in 30–40%. Other mental health issues such as anxiety disorder and substance use disorder are commonly associated.
The cause is not clearly understood, but both genetic and environmental factors play a role. Many genes of small effect contribute to risk. Environmental factors include long term stress and a history of childhood abuse. It is divided into bipolar I disorder if there is at least one manic episode and bipolar II disorder if there are at least one hypomanic episode and one major depressive episode. In those with less severe symptoms of a prolonged duration the condition cyclothymic disorder may be present. If due to drugs or medical problems it is classified separately. Other conditions that may present in a similar manner include substance use disorder, personality disorders, attention deficit hyperactivity disorder, and schizophrenia as well as a number of medical conditions. Blood tests or medical imaging can be done to rule out other problems, although medical testing is not mandatory for a diagnosis.

Mitochondrial diseases are a group of disorders caused by genetic mutations. In this animation, Nature Video finds out how these diseases arise, and how new techniques can stop them being passed on from mother to child.

Royal Society GlaxoSmithKline Prize Lecture given by Professor Adrian Bird CBE FMedSci FRS on Tuesday 22 January 2013. Adrian Bird CBE FMedSci FRS is the Buchanan Chair of Genetics at the University of Edinburgh. The human genome sequence has been available for more than a decade, but its significance is still not fully understood. While most human genes have been identified, there is much to learn about the DNA signals that control them. This lecture described an unusually short DNA sequence, just two base pairs long, CG, which occurs in several chemically different forms. Defects in signalling by CG are implicated in disease. For example, the autism spectrum disorder Rett syndrome is caused by loss of a protein that reads methylated CG and affects the activity of genes. The Royal Soci...

Five years ago, TED Fellow Jen Brea became progressively ill with myalgic encephalomyelitis, commonly known as chronic fatigue syndrome, a debilitating illness that severely impairs normal activities and on bad days makes even the rustling of bed sheets unbearable. In this poignant talk, Brea describes the obstacles she's encountered in seeking treatment for her condition, whose root causes and physical effects we don't fully understand, as well as her mission to document through film the lives of patients that medicine struggles to treat. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less).
