Analysis Of Trisomy 13 Not Always Genetics - 873 Words

Trisomy 13: Not Always Genetics Understanding the way our body is formed starting from the chromosomes to organ systems allows nurses to recognize genetic abnormalities. Comprehension of how these abnormalities change a person’s outward appearance and their bodily functions is expected of nurses. The aim of this paper is to explain how genetics and knowledge of genetics play a role in community nursing, and nursing in general. Genetics is the study of genes, genetic variation, and heredity of living organisms. Genes are the sets of chromosomes combined from the mother and father formed into the new set for the offspring. Sets of alleles forming the traits given to an offspring are called either genotypes, or when observable outwardly on the progeny they are called its phenotype. Traits are heterozygous as a gene with one allele is dominant, as its qualities dominate the phenotype of the organism, and the other allele is recessive. Recessive alleles qualities recede and are not observed over the domina nt allele. Some alleles do not have complete dominance and instead have incomplete dominance by expressing an intermediate phenotype, or codominance by expressing both alleles at once. Combinations of traits and genes make up the different faces and characteristics seen in our world and communities. One person even if related, unless from identical chromosomes, will not ever look the same as another human being (Tortora Derrickson, 2008).

T13 is characterized by the presence of an assortment of heart and brain malformation in newborns. Children with the disease are often born with multiple birth defects that are normally associated with T13 but not limited to it, including small eyes, undescended testicles, cleft lip/palate, and they consistently exhibit signs of mental deficiency and/orRead MoreThe Ethical Concept Of Genetic Engineering1157 Words   |  5 PagesThis assignment will discuss the ethical concept of genetic engineering and how it demonstrates its relevance to midwifery professional practice and maternity care. Before analysing genetic engineering and looking at the arguments as to whether it is ethically right, an understanding of what the terms and lawful procedu res mean should be determined. In order to construct this assignment, multiple resources were accessed. These resources included analysing books, both hard copies and electronicallyRead MoreGenetic Testing : Types Of Medical And Forensic Tests1715 Words   |  7 Pages Genetic Testing WHAT IS GENETIC TESTING? Genetic Testing is the process of using medical and forensic tests to identify and analyse a human, animal or plant DNA sequence. It can reveal changes or mutations in your genes that may result in illness and disease. TYPES OF TESTING Presymptomatic and predictive testing If you have a family history of a condition, undergoing genetic testing before you have symptoms may reveal if you re at risk for developing that condition Carrier testing If youRead MoreThe Genetic And Clinical Risk Factors For Explosion Phase Progression Of Chronic Leukemia1922 Words   |  8 Pagescarry an inherent risk of transformation to an accelerated-phase disease, as well as ultimately to acute leukemia. The likelihood of disease evolution is mitigated by various clinical, biological and genetic factors, as well as the by the underlying initial MPN diagnosis. Here we review the genetic and clinical risk factors for blast-phase progression of chronic-phase Phliadelphia-chromosome negative MPNs, as well as therapeutic outcomes to date. We also review the key pathologic findings in disease
