Gene mutation can cause several diseases such as Sickle cell anemia‚ cystic fibrosis‚Tay- sachs disease‚ hemophilia and some cancers. Gene Mutation could be categorized in 2 ways 1.

At this point in my clinicals‚ I knew what questions to ask with certain disease processes‚ but I was still uncomfortable with how to ask and leave it open ended so the patient could expand on the topic. We were going into the patient’s room for both manual CPT and vibratory percussion due to a pneumothorax. She was a pleasant patient who was awaiting our arrival to perform her CPT. This would be my first patient experience with me performing CPT on a cystic fibrosis patient

time undergoes a various morphologic changes of fibrocystic disease. The peak incidence is between 35 and 50 years of age and it is rare before 25 years. The term embraces a spectrum of histologic changes‚ and may encompass many patients who have cystic lesions detected clinically or sclerotic breast lesions detected on mammography. Histologically it is characterized by overgrowth of both fibrous stroma‚ and of epithelial elements i.e. ducts and lobules‚ in differing proportions. These changes

individuals. Cystic fibrosis Is an illness which is genetically passed on‚ it is caused by a defective gene. The cystic fibrosis gene is recessive‚ this means that if a child has a parent who carries the gene they will not get the illness unless the other parent also carries the gene however‚ there is a 1 in 4 chance of catching the disease. Cystic fibrosis causes excess production of a defective protein that causes the lungs to become full of sticky thick mucus. Sufferers of Cystic fibrosis can have

Pre-implantation Genetic Diagnosis (PGD) is a prenatal diagnosis specifically for parents with a high risk of producing an offspring with a serious genetic disorder. This is a socio scientific issue as there are many viewpoints and opinion surrounding this topic. PGD is only permitted if there is a 25% chance of inheritance of the serious condition or if there is a high chance of inheriting chromosome abnormalities which is associated to recurrent miscarriages or advanced maternal age.

P2 – Effects of five life factors on individual development Genetic factors such as cystic fibrosis for example‚ are life factors which can affect the development of an individual. It can affect an individual at any age and is caused by a faulty gene that is passed from the parents to the child. The faulty gene allows too much salt and not enough water into cells and makes a build up of thick‚ sticky mucus in the body’s tubes. This can cause blockages in the body’s tubes and passageways‚ and causes

are speaking about genes and genetics. We’re also learning about genetic disorders which happen when one person is missing a chromosome or has an extra chromosome. Examples can be Down syndrome or Turner Syndrome. This also relates to punnett squares. In punnett squares you find the probability of characteristics and you can use one to find out the probability of a person developing alcoholism. This article relates to class and can possibly relate to anybody’s life. This article taught me that alcoholism
