Cct Is A Highly Heritable And One Of The Most Correlated Quntitive Trait ( Ref )

As humans, we don't always see with our eyes, but often with our imagination (Grunwald, 2016). Often times as people we never realize how useful our vision really is to us. You really don't think about something like that until it would actual happen to you. Throughout this essay, you will learn how the body is affected by Macular Degeneration (MD). Different signs and symptoms, as well as the etiology of MD, will be discussed. In the following, diagnosis tests and treatments may also be listed in order to help others who would like to know more about MD. Not to mention, you will learn the incidence and progression of MD. Furthermore, information though agencies and associations, as well as new research about MD will be given.

Firstly, many forms of glaucoma are related to genetic mutations. For example, elevated IOP and glaucoma in DBA/2J mice is caused by recessive mutations in the genes Tyrp1 and Gpnmb, and the human genes MYOC and GLC1A are associated with human autosomal dominant recessive glaucoma and with human adult-onset glaucoma (Jakobs, Libby, Ben, John, & Masland, 2005). Gene therapy for people with the glaucomatous mutations should be explored as a possible preventative measure for future generations. Secondly, the changes in morphology of RGCs in glaucomatous eyes may be explored. Although several structural changes have already been observed, such as higher-order dendrite disappearance and overall shrinkage of RGCs, the effect of these changes in morphology on physiology has not yet been documented. Moreover, it is still unknown whether living RGCs in glaucomatous eyes adapt to the widespread cell loss and change in structure. Finally, stem cell therapy should be explored as a possible regenerative treatment for glaucoma patients. Although RGCs do not undergo mitosis, it may be possible for stem cells to develop and emulate their morphology and physiology. It may equally be possible for stem cells to help regenerate the damaged optic nerve. The many studies on the neural impact of glaucoma have reached a stage where, with the advances in cellular research and biotechnology, novel treatment options may be explored on this extremely common neurodegenerative

The authors state that the clinical diagnosis for the disease was confirmed by conduction a whole exome sequencing. With this sequencing they were able to detect multiple heterozygous mutations. These mutations were: a missense variation

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

CD117 is a membrane tyrosine kinase receptor (Type III receptor tyrosine kinase family), encoded by the c-kit proto-oncogene. The Type I transmembrane glycoprotein locates on chromosome 4q11 and 4q12 and has a total length of 90 kb. It has a molecular mass of 145 kDa. The extra-cellular domain consists of 519 amino acids. It contains 5 Ig-like domains. D1-D3 are responsible for c-kit binding to stem cell factor, and D4 and D5 are the dimerization domains. The transmembrane region consists of 23 amino acids and the juxta-membrane domain is made up of 433 amino acids. The tyrosine kinase domain is inserted by approximately 80 amino acid residues.

This gene provides information for making a protein that regulates the transforming growth factor beta (TGF-β) signaling pathway. The TGF-β pathway regulates many processes, including cell growth and proliferation, the process by which cells mature to carry out special functions (differentiation), cell motility, and apoptosis. By attaching to certain proteins , the SKI protein blocks TGF-β signaling. The SKI protein is found in many cell types allover the body and appears to have a role in the development of many tissues, including the skull, other bones, skin, and brain.

The pedigreed family shows an excessive portion of family members with cardiovascular disease (coronary artery disease, cerebrovascular disease, peripheral vascular disease) in one half of the subjectssubject’s lineage. The paternal side of the target subject has a sibling, first cousin, uncle, three great uncles, two aunts and great – great grandfather with some form of cardiovascular disease. The maternal side has only a grandfather with cardiovascular disease. If the trait in question Lp(a) were autosomal dominant one would expect around a 50% gene expression in the studied group. Nine of twenty in this particular lineage currently show or have shown disease and two subjects are unable to assess (UTA). This would suggest autosomal dominant inheritance in the paternal half of the target subject lineage with a suspected two subject incidence yet to be found or attributed.

Choice “C” is the best answer. First- and second-degree relatives of patients with confirmed Wilson disease must be screened for this condition. This condition is due to mutations in the Wilson disease protein (ATP7B) gene. The inheritance pattern is autosomal recessive. A single abnormal copy of the gene is present in 1 in 100 people, who do not develop any symptoms. If a child inherits the gene from both parents, the child may develop Wilson disease. Linkage analysis has been used in family studies for presymptomatic testing; however, the multiplicity of mutations (>200 mutations of ATP7B have been identified) would require screening in a large population of individuals without affected family members, making this endeavor impractical. Therefore, the use of molecular testing is currently limited to screening of family members for an identified mutation detected in the index patient.

LA exploits the fact that genes have a tendency to be inherited together because they are located close to each other. After identification of a linkage, all genes in the linked region need to be identified and in this manner candidate genes of interest for a disease can be established. LA has been successful in localizing chromosomal regions containing highly penetrant genetic variants. However, in a common disease, such as OA, the success of LA is very limited for a number of reasons, including the low power of identification of genes with modest effects and the large impact of environmental influences (Risch et al., 1996).

There are autosomal dominant and autosomal recessive forms of OI that causes the production of

     Basically what my research is stating is that there is a major genetic component that contributes to this disease. There are three general types of hereditary Macular Degeneration. The first is called early onset. This is when you get it when you are four years of age up to seven. In this type both parents and their children can be affected. This means it is dominantly inherited. Most of the time this is called Best Disease or Viteliform Macular Degeneration.

Three other genes make proteins that are also involved in melanin pigment formation and albinism, but the exact role of these proteins remains unknown. These genes are the P gene on chromosome 15, the Hermansky--Pudlak syndrome gene on chromosome 10, and the ocular albinism gene on the X chromosome.

The eye is an organ that provides an organism with the ability to visualise its surroundings. It captures light and transmits the information to the brain to be processed. The eye is composed of numerous components that give rise a complex structure. These components have specific roles and ensure that the eye functions properly. However, the eye can lose its function through the degeneration of several tissues which may lead to permanent blindness, giving rise to diseases like age-related macular degeneration (AMD), Stargardt disease (SD) and Retinitis pigmentosa (RP) [12-14].

It is characterized by bilateral optic atrophy with insidious visual loss in 1st to 2nd decade. As the name suggests, it is inherited in Autosomal dominant pattern. Systemic abnormalities are usually absent; however, associations with sensorineural hearing loss are documented.

The eye is a very complicated part of the body. It is not as simple as they look they have complicated mechanisms inside. There is a part of the that is like a pathway for the aqueous humor to exit the eye. The aqueous humor is behind the lens and the ciliary muscles. when the ciliary muscle are relaxed it allow the aqueous humor flow pass the lens and ciliary muscles. After it go out the puple it can exit the eye in two ways the uveoscleral or the conventual through the trabecular (TM) or conventional pathway. The uveoscleral way is seeping through the ciliary muscles. The TM is an important function of the eye. It has the scams canal which is a outlet it has K+,Na+2cl- ions that let the aqueous humor go through. This
