The Fragile X syndrome and Duchenne muscular dystrophy (DMD) disease comparation

The human genome is split into 23 pairs chromosomes (DNA), which atomic number 18 coiled in a spiral ladder lineament through nucleotide total heat bases (cytosine-c, guanine-g, thymine-t, adenine-a) (fig1 below). Human cells brook 46 chromosomes (fig 2 below) - 22 pairs of autosomes chromosomes 1 to 22 and two sexual practice chromosomes X and y or X and X depending sex activity (sex-linked). Within these chromosomes are or so 30,000 components that controls and construct the electric reed organs in the body.

Of these, 95% affect males as it reflects the presence of the abnormal element on the X chromosome, which is march in two copies in egg-producing(prenominal)s and one in males. Males inherit the X chromosome from their receive and the Y chromosome from their beginner. Since this is the case, abnormalities on the X chromosome from the mother provide usually sheer as a sickness within 50% of her males offsprings. Since females fool a chromosomal manufacture of XX, inheriting an X chromosome with sickness mutations in it generally will not produce the illness condition. The healthy X chromosome that the female has inherited from her other farm male masks the diseased X chromosome.

The female with one mutated X chromosome would be known as a mailman because she peck pass the mutation onto her children, though she may not be directly impact by it. An X-linked disease could affect a female, in a depress percentage, if her mother is a pallbearer and the disease affects her father. If her mother and her father are both affect with the disease, she will most sure as shooting be afflicted with the disease as well. Despite these many sex-linked diseases, at present antenatal diagnosis can specifically be made in fewer than 40 diseases. These sex-linked diseases of single...
