The mother, who is a carrier, inherits an X-Linked or sex-linked faulty gene. The result is producing an affected son and or a daughter being a carrier. The second way is an affected male producing children, particularly daughters. All daughters born to fathers with x-linked muscular dystrophy will be carriers; on the contrary their sons will be unaffected. Scientists link this to a genetic mutation in the gene, appearing most often for the first time in a family.

Listener Relevance: Duchenne Muscular Dystrophy (DMD), is more common than people think and chances are sooner or later you will know of or see somebody affected by this disease.

Fragile X Syndrome is a genetic condition causing intellectual disability, behavioural and learning challenges and various physical characteristics, it occurs in both genders but effects males more. Also is the most common gene for Autism worldwide, every week in Australia one child is born who is fully affected and 20 children are born who are carriers. It is estimated that 5 per cent of people with a diagnosis of an Autism Spectrum disorder also have Fragile X.

Duchenne Muscular Dystrophy is a genetic disorder that is passed on through the x chromosomes. Only men are

However, if Ben’s parents have decided to have other children, their children run the risk of having DMD or being a carrier of DMD. There is no way to reduce these risks, but there is a chance that their children will not have the same problems as Ben.

The Mitchell MD100 is an impressive 12-string acoustic guitar. It has a true dreadnought-sized body. This instrument combines a lot of high-quality features into one wonderful package. It makes great music on stage or even just jamming at home.

Duchenne Muscular Dystrophy has the potential to be inherited from previous generations (National Human Genome Research Institute, 2013). The disease is sex-linked and inherited on the X chromosome in a recessive fashion. Males who only have one X and one Y chromosome are most commonly affected

Duchenne Muscular Dystrophy is an X-linked genetic disorder caused by a genetic mutation in the dystrophin gene. The disorder is recessive, therefore males are more at risk for displaying the mutation than women. However, women can be carriers and have mild effects. Duchenne Muscular Dystrophy affects the neuromuscular systems, which can result in deterioration of muscles and eventually death.1 The disorder usually presents itself in early childhood, and can affect the respiratory and cardio systems. The disease can cause spinal problems, respiratory problems, intellectual disability, and cardiac disease which is the main cause of death.4

Meiosis, the process of cell division in creating sex cells, is what plays into Duchenne. When a sperm cell meets an egg cell, that cell has a 50% to gain traits from the mom’s x chromosome, and 100% probability to gain traits from the dad’s y chromosome. Duchenne is a genetically inherited mutation from the x chromosome; which means during meiosis, at least one of the mom’s chromosome had to have been carrying the mutation. The child has a 50% chance of developing

The genetic disease known as Muscular Dystrophy first appeared in history in the year 1830. It was included in a written report by the Scottish Neurologist Sir Charles Bell. The disease soon became more prominent, where it appeared in several medical journals from the 1850’s and onwards. Several young boys were described as having a weakness which progressively worsened, along with problems walking. The disease led to their eventual premature deaths. A French Neurologist known as Guillaume Duchenne studied 13 boys who all had the most common and severe form of Muscular Dystrophy, soon to be known as Duchenne Muscular Dystrophy (NIH 2016). Muscular dystrophy refers to a group of more than 30 genetic diseases including Distal MD, Emery-Dreifuss MD, Facioscapulohumeral MD, Limb-girdle MD, Becker MD, Congenital MD, Myotonic MD and Oculopharyngeal MD. This review however will just focus on Duchenne muscular dystrophy.

A genetic disorder is a mutation in an organisms DNA. It is caused by a change in the sequencing of the nucleotides that make up a specific gene. The genetic disorder can be inherited by offspring, but it may or may not show in the offspring depending on whether the genetic disorder is a dominate or recessive allele. There are many genetic disorders that humans develop and inherit. Some disorders cause improvements within the human species while others cause severe retardation of the human species. In this paper, the genetic disorder Angelman Syndrome will be discussed.

In 1943 two men, Martin and Bell discovered a gene condition called Fragile X Syndrome. 2 Fragile X Syndrome (FXS) is a genetic condition, which may cause an intellectual disability, behavioural and learning difficulties and various other physical characterstics.1 It occurs when the female gene (X-gene) is repeated over 50-200 times, this is called Fragile X permutation. 1 In 1969, Herbert Lubs established the chromosomal test for Fragile X Syndrome. Fragile X Syndrome is an inherited condition in which the X chromosome is passed on from the parent to the child. If the woman has the affect X, they will have an increased chance for passing the gene on but as men have an Y as well as an X chromosome, if they have Fragile X Syndrome, their sons won’t be affected as they have their fathers Y chromosome. It is the most common form of inherited intellectual disability in males and a major cause of intellectual disability in females.

A genetic disorder, such as DiGeorge syndrome, is an illness caused by one or more abnormalities, which can be passed down through parents, DNA, or mutations. DiGeorge syndrome (DGS) is a rare type of a genetic disorder which is caused by the deletion of chromosome 22. DiGeorge syndrome affects many parts of the body and has a prevalence of 1: 4000

X-linked dominant disorders are produced by changes of the X chromosome on the gene. Females have two X chromosomes. A mutation in one of the two copies of the gene of each cell is enough to cause a disorder. Males only have one X chromosome, so metamorphosis in only one copy of the gene from each cell is a foundation for the disorder as well. Males can also not pass the gene on to another male, such as their son. It is also not uncommon for males to experience more severe symptoms or reactions of the disorder than that of a female. An example

A Distrofia Muscular de Duchenne é uma doença hereditária, caracterizada por uma degeneração muscular progressiva, causando fraqueza (Emery, 1993). Por ser uma condição recessiva ligada ao cromossomo “X”, a DMD afeta predominantemente meninos, e estudos recentes reportam que sua incidência geral corresponde a 1:4087 (Mendell at al., 2012).
