Familial Hypercholesterolemia: A Genetic Family History Familial hypercholesterolaemia (FH) is an autosomal, dominant, inherited disorder of lipoprotein metabolism that results in elevated low-density lipoprotein cholesterol (LDL) in plasma concentration (Henderson, O’kane, McGilligan, & Waterson, 2016). FH can dramatically increased risk of atherosclerosis, which can lead to a common genetic cause of premature coronary heart disease (CHD). It is crucial for patients to know their genetic family history and genogram to have early diagnosis, treatments, and follow ups that may delay the complications of the course of FH and consequently CHD or other cardiovascular diseases (CVD). The proband is paramount in identifying other at-risk individuals; hence, enabling, and educating these patients to discuss the risk with family members is essential. Nurses need the knowledge of FH genetic standpoint to educate patients and make appropriate referrals for individuals in need of genetic counseling. The purpose of this paper is to complete a genetic family history of an individual of choice. Construct a genogram and attach it to this paper as an Appendix. Provide and explanation of the genogram …show more content…
The lipoprotein gene mutation has a penetrance of greater than 90% (Henderson et al., 2016). Heterozygosity takes place when an individual has two dissimilar alleles of a gene. A single dominant gene can manifest itself in a heterozygous person particularly when there is high penetrance property. This is the reason why multiple generation can be affected by the FH disorder as seen in the proband and family members of the followed case discussion. Monogenic FH is largely attributed to mutations in the LDL-receptor (LDLR), apolipoprotein B (APOB), and proprotein convertase, subtilisin/kexin-type 9 [PCSK9] genes (Brautbar et al.,
Heterozygous familial hypercholesterolemia current drug therapy statins, bile acid sequestrates, or other lipid lowering agents that lower cholesterol levels with relative success. Homozygous familial hypercholesterolemia (HoFH) is not treated well with standard lipid-lowering medications and needs costly methods to lower LDL-like apheresis or a liver transplant. HoFH occurs approximately 1 in 1 million births, creating a small population to gather data about treatments for this rare disease state. 1 Studies have shown that the best role of Juxtapid in familial hypercholesterolemia is as adjunctive therapy
This examination compiled the following information: Grandmother “C” has BRCA1 trait resulting in double mastectomy at age 35, prior to diagnosis Grandmother “C” only medical condition was hypertension,. Mother “M” information was obtained. Mother "M" provided the
Catherine and I filled out the Medical Health History of the Family and created a family genogram.
As controversy rises over the ability to test embryos for genetic defects one must chose a side. In this essay I will be examining the debate over the ability to screen for familial hypercholesterolemia in embryos. Familial hypercholesterolemia is a condition which often kills children before puberty. This condition causes elevated cholesterol and can cause angina at a young age. Many children with this disease die at a young age and most suffer at least one heart attack by their thirties. There is however, a treatable version of this disease which is the heterozygous variation. 1 in 500 people develop the heterozygous disease while 1 in 250,000 people develop the more serious homozygous variation. Critics argue that the ability to test for Familial hypercholesterolemia will allow couples to destroy embryos that have the potential to live healthy lives. In this essay I will argue that genetic testing for familial hypercholesterolemia is permissible.
Genetics - Certain genes can lead someone to have a higher risk of type 1 diabetes
Homozygous familial hypercholesterolemia is a genetic disorder inherited by parent or parents at birth in an autosomal dominant way. When the mutated gene is passed down through one parent it is known to be heterozygous but when both parents carry this mutated gene it causes a higher risk for the child to be born with a homozygous condition which is found to be a lot worse. Sufferers of Familial hypercholesterolemia also known as FH, have high amount of cholesterol from birth which in effect can cause early developmental problems with the heart in the future causing Atherosclerosis or CHD.
The National Institute of Health (2014) listed the most common form of familial hyperinsulinism to be an autosomal recessive genetic defect that is common among the Ashkenazi Jewish population. This condition affects 1 in 66 carriers who are Ashkenazi Jews since they have reported consanguineous marriages (NIH, 2014). Among Ashkenazi Jews, two single ABCC8 mutations account for 90 percent of cases of familiar hyperinsulinism (Mazor-Aronovitch, et al, 2007). The incidence of FHI in individuals of northern European descendants is approximately 1:30,000 live births. The incidence is increased in genetically isolated populations with a high prevalence of consanguinity (UpToDate.com).
This paper explores the concept of a familial genogram and the insight a familial genogram can provide. I have utilized three published articles to help clarify what a genogram is and what it is used for, what hypothyroidism is and its genetic components, and the connection hypothyroidism has to mental health. I have attached a familial genogram that explores the prevalence of hypothyroidism in my family tree. My diagram begins with my grandparents, through my parents, aunts and uncles, down to myself, my siblings and my cousins.
The propensity for specific disease processes are found when analyzing a client’s family tree history. Typically, completing a genogram with at least three generations can show which disease processes show a pattern in a specific family tree. As figure 1 shows, the current generation has a predisposition for cardiovascular disease, diabetes, and cancer. The history complied spans four generations, with three generations on the paternal side, father, grandfather, grandmother, and great-grandfather, contracting heart disease, either suffering from a heart attack, having high blood pressure, or high cholesterol. On the maternal side, there is little information past the second generation. However,
Hypercholesterolemia is both a dominant and recessive disorder. The genotypes for the dominant disorder would be heterozygous and for the recessive disorder the genotype would be a Homozygous recessive. The two genotypes in the hypercholesterolemia disorder represent the severity of its affects will be. Both of heterozygous and homozygous version of hypercholesterolemia cause a loss of low density lipoproteins. Low density Lipoproteins are receptors in the liver cell that breaks down cholesterol carried in the blood, the loss of lipoproteins can cause severe consequences in an individual. In a heterozygous version of hypercholesterolemia an individual would have blood levels that are twice than normal due to the loss of lipoproteins. This would cause an individual to have an increase in cholesterol build up in the artery walls which can lead to serious heart problems. Homozygous recessive version is the worst
hereditary disorder of Caucasians in the United States and is the most common cause of chronic
One effective way the therapist could help our family would be using a creative genogram. “The creative genogram, used as a tool in teaching or therapy simultaneously generated diagnostic information created a space for reflective processes, either by reframing problems or direct problem solving” (Huss & Cwikel, 2008, p. 179). The therapist and family could recognize historical patterns that could be affecting how our family perceives our situation. Therefore, using a creative genogram can provide information about our family’s patterns over generations that contain history occurrences, such as relationships among family members (Huss & Cwikel, 2008). The genogram can help our family with self-awareness, overwhelming emotions, and help shape
After examining my family’s health genome, I am able to identify strengths and weaknesses of my family’s health. For strengths, my mother’s side has little to no health conditions or concerns. Also, neither side has had a history of cancer. However, there are some weaknesses in my family health tree. My biggest concern for my immediate family, and my dad’s side is hypertension and heart disease. Even though this may just be due to lifestyle factors, I think there may be a genetic factor involved as well. This is because hypertension appears in both my aunt and dad.
A genogram is a type of family tree, but with more detailed information. It is often used as a diagnostic and assessment tool by physicians or counselors to obtain individual and family history in order to help in the establishment of a diagnosis and treatment plan.
The family that is being observed for this assignment is headed by a married couple who has been together for a little over 40th years. Cliff Barnes a 61 year old male is married to Amy Barnes 66 years old. Their immediate household composition includes Amy Barnes’s 44 year son from a previous relationship, her 22 year old grandson and the couple’s 15 year old adopted daughter. I have included the immediate family members in the attached genogram because they play a major role in the family dynamics.
