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 quality through nucleotide henry 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 depend on chromosomes X and y or X and X depending gender (sex-linked). Within these chromosomes are most 30,000 components that controls and construct the electric electric organs in the body. There are over approximately 250 recognized sex-linked infirmitys, affecting every organ system. Of these, 95% affect males as it reflects the presence of the abnormal element on the X chromosome, which is set in two copies in distaffs and one in males. Males acquire the X chromosome from their scram and the Y chromosome from their father. Since this is the case, abnormalities on the X chromosome from the mother volition usually discernible as a rowdyism within 50% of her males offsprings. Since females charter a chromosomal counterbalance of XX, inheriting an X chromosome with unhealthiness mutations in it generally will not produce the infirmity condition. The healthy X chromosome that the female has inherited from her other harass male masks the unhealthinessd X chromosome.

The female with one mutated X chromosome would be known as a mailman because she lot 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 discredit percentage, if her mother is a attack aircraft carrier and the disease affects her father. If her mother and her father are both change with the disease, she will most for certain be afflicted with the disease as well. Despite these many sex-linked diseases, at present antepartum diagnosis can specifically be made in fewer than 40 diseases. These sex-linked diseases of single...
