Factors Affecting The Infection Of Chromosome 16

Frame shift mutations are the type of mutation caused by the addition or deletion of a base pair in the DNA resulting in the translation of the genetic code in an unnatural reading frame from the position of the mutation to the end of the gene. In the mutations, we added and deleted beads resulting in an incorrect sentence that does not make sense.

De novo mutations account for 80-90% of all cases of ACH (1, 4, 7, 8, 11). Recent research has determined that increased paternal age correlates to this specific mutation occuring (4, 7, 11, 19). The maternal age seems to have no effect, meaning that the de novo mutation occurs during spermatogenesis (20). This has also been studied and each affected individual was found to have received the mutated chromosome paternally (21). There has only been one documented case of an

D1S80 locus is placed on the short arm of the chromosome 1. This locus does not code for the arrangement for protein, yet it codes for a series of tandem repeats of 16 bp in human. Distinctive number of this allele has different number of repeats. These quantities of repeats are exceptional to every human. Primer

Roi1 is also known as rough eye and it is a dominant mutation which causes abnormal patterns and genomic inversions in the D.melanogaster eye (Chanut et al. 2002). The recombination map location of the Roi1 is 2-54.7. The gl3 is an allele and the Gl1 is a protein for the gl gene, also known as glass, both are located at 3-63.1. The gl gene is known to reduce the size of the adult D. melanogaster eye. Even though the gl3 is a weak allele for the glass gene it produces a really pigmented eye ( Ma et al. 1996). The rh1 gene is known as rhodopsin; the recombination map location is at 3.66.4. Rh1 causes degeneration of the D. melanogaster retina (Kristaponyete et al. 2012). Rho1 also known as the rhomboid gene, is closely related to the roughed (ru); which happens to be a recessive eye mutation (Wasserman

The testes are one of the physical differences that are seen within men that has this disorder with the assumption that theses phenotypic differences are contingent to the proximity of the SRY gene in addition to the absence of the rearrangement that directly modifies SRY gene expression. The rearrangement of the SRY gene can cause a cascade of effects especially with the expression of the SOX 9. The influence of SOX 9 aids in the function of testes development. PCR assay have been utilized in order to reveal the significance of SOX 9 and how it aids in the development. The PCR assay sequenced genes that were used in the coding section of SOX 9, but the specific strain that was used not clearly defined. It was shown through three assays that it confirmed the idea that if the SRY gene were not present it would aid in the mutation of testicular development. Although this experiment was proved to show definite results, it did not show what the three independent PCRs were specifically targeting in the assay. The author was trying to prove that without the SRY gene a male phenotype would still develop, but the physical appearances of these men would be slightly modified to be less normal with small testes that were deemed infertile. The results that were displayed has risen more questions then finding a closer clue as to how the SRY gene could make a man infertile with malformation of the testes. Instead it questioned whether or not the SRY gene could ultimately be the cause of infertility despite having the mutation

In inherited diseases repeat expansions occur in parental germ line and while in healthy individuals TNR are short and stable, in affected families the tracts are longer, unstable, with the tendency to add repeated units with generation and during patients’ lifetime (Castel et al., 2010).

Testicular cancer is very rare it, and prostate cancer it can affect males age 15-35. Risk factors are history of one or both testes fail to descend, family history and is more common in white male than African American men. Treatments for prostate cancer depend on the aggressiveness of cancer and can range from surgery, radiation, and hormonal therapy. BPH treatments depend on the severity of is symptoms although it cannot be cured medications can help to shrink the prostate and surgical removal of the central part of the prostate can relive the symptoms, close monitoring until symptoms become a problem. BPH is caused by increased levels of testosterone at occur normally with increasing age, and is the most common cause of urinary obstruction of men 40 and older. Prostate cancer it is not entirely understood but it is caused by an unregulated growth of prostate cells, and is the most common male cancer. Common risk factors are hereditary; an increase age of 50 and older and is more commonly found in African American men then white. Treatments for testicular cancer depend on type of cancer or malignant or non-malignant, and stage of cancer but may include removal of the testicle and nearby lymph nodes sometimes fallowed by radiation

A. Dominant pathogenic mutations display their traits despite another copy remains present. The lethal form of keratitis-ichthyosis-deafness (KID) syndrome is caused by the reversion of the GJB2 nonsense mutation p.Tyr136X that would otherwise have confined the effect of another dominant lethal mutation, p.Gly45Glu, in the same allele

With an abnormal number of repeats the trinucleotide sequence becomes more unstable and disease symptoms grow to be more visible. Myotonic dystrophy II (DM2) is a mutation of cellular nucleic acid binding protein (CNBP), or zinc finger protein 9. The functions of both proteins, CNBP and DMPK are uncertain, however they can be found in multiple organs and tissues in the body, including the brain, cardiac, and skeletal muscles (Ueada, Ohno & Kobayashi, 2000). Myotonic dystrophy is located on chromosome 19q13.3 and is a result of an abnormal repeat of the DNA sequence. According to Mckusick & Hartz (1986) People with DM2 can have from 75 to more than 11,000 CCTG repeats. Both DM1 and DM2 are autosomal dominant inheritable disease, which can be passed along to offspring if the parent is affected, at a 50% probability. Myotonic dystrophy is unique from most provided that “disease-causing alleles may expand in length during gametogenesis, resulting in the transmission of longer trinucleotide repeat alleles that may be associated with earlier onset and more severe disease than that observed in the parent” (Bird et al., 1999).

why he developed this type of cancer. "Scientists have identified more than 300 altered genes

Moreover, common, known and synonymous variants were not included in their final analysis. In our study we will investigate all variant types because our aim is to determine what pathways variants occupy and their interactions with other variants. Eliminating variants may well result in lose of

screenings in multiple populations, it was concluded that the most common mutation shared between Caucasians is R864X.

In sequence one I found that it was the protein BRCA2. This protein is responsible for repairing DNA, it is a tumor suppressor gene. A tumor suppressor helps cells from growing and dividing too quickly and out of control. BRCA2 also helps regulate cytokinesis. If something is wrong with this protein at any point, there can be a risk to develop breast, ovarian, and prostate cancer. BRCA2 is involved in the maintenance of genome stability, specifically the homologous recombination for DNA repair. More than one thousand eight hundred cases have been presented to doctors for breast cancer. It has been found to come in clusters with families, but not always. Men are at risk of prostate cancer at an early age and is said to be very aggressive. Men

Based upon observation of the F1 generation, we hypothesize that the inheritance of the white-eye (W) mutation is sex-linked and recessive wild type.

al. 2015) since retinal binding and functional group interaction is delicate and may vary with protein mutations.
