Mccune Albright Syndrome Summary

Activators of GRK would cause phosphorylation of serine and threonine residues, which can then bind arrestin proteins, preventing reactivation of the signaling pathway.

Vitiligo is a chronic skin disorder that affects the pigmentation of the skin. Pigment is what gives the skin color and is produced by cells called melanocytes. In the disorder, the body attacks the melanocytes resulting in the loss of color in patchy areas. When the color is lost, the affected area becomes a white irregular shaped patch on the outer layer of the skin. Vitiligo can affect a very small portion of the body or affect up to fifty percent of the skin. The most common areas of the body affected by the disorder include the hands, feet, arms, face and sometimes the genitalia. This illness can be treated but it cannot be cured

Fibrodysplasia ossificans progressiva also known as FOP is a one of the rarest, most disabling genetic bone conditions known to medicine. FOP causes muscles, tendons, ligaments, and other connective tissues to turn in to bone. Movement becomes limited in the affected areas of the body. People with FOP typically have malformed toes at birth, meaning the big toe is typically shorter than normal and abnormally turned outward in a position called a valgus deviation. Symptoms of FOP start to show up in early childhood. Most people with FOP develop painful tumor-like swellings also known as fibrous nodules. The fibrous nodules are visible on the neck, shoulders, and back.

Cushing’s syndrome (also known as Cushing’s disease) is a disorder of the endocrine system. The disease is caused by the excess production, or in some cases excess consumption, of the hormone cortisol. The disease can be caused by tumors on the pituitary gland, adrenal gland complications, and the usage of corticosteroids. Cushing’s syndrome is difficult to diagnose due to its rarity, and there is no specific test to diagnose it. Symptoms of Cushing’s syndrome include obesity, “moon face”, slow growth rate, skin changes, and muscle and bone changes. Cushing’s syndrome is treatable. Some of the treatments include surgery, chemotherapy, and radiation.

Lynch syndrome (LS) is a genetic disorder which increases the risk for other types of cancers and can have

Talking and eating may become difficult as the mouth becomes affected. As time goes on, patients with FOP may become malnourished because of the inability to eat. They also develop breathing difficulties as a result of extra bone formation around the rib cage that restricts lungs from expanding when exhaling. Symptoms of FOP are; movement becomes extremely restricted as bone grows into joints, and the spine can become deformed or fused together. Due to limited mobility balance and coordination problems can occur and can lead to injury due to falling. A minor injury can cause more inflammation and bone growth .

The disease affects numerous systems both internally and externally in the patient due to copper metabolism deficiencies. The main physical phenotypes are sparse and steel colored hair that is often kinky, pale skin,

Vitiligo is a common dermatological disorder characterized by acquired, idiopathic, progressive, circumscribed hypomelanosis of the skin and hair, with total absence of melanocytes microscopically.[1] Various physiological, biochemical, histochemical and enzymatic studies have been done to find out the cause of the disease.[2] Genes certainly play a role in all aspects of vitiligo pathogenesis, even response to environmental triggers, and so genetics really should not be separated out as a distinct phenomenon. [3],[4] In the past few years, studies of the genetic epidemiology of generalized vitiligo have led to the recognition that vitiligo is part of a broader, genetically determined, autoimmune, and auto inflammatory diathesis. [3],[5] The pathogenesis of this disorder is uncertain, but it appears to be dependent on the interaction of genetic, immunological, and neurological

It is action is mediated by Protein Kinase G (PKG) , a cGMP-dependent protein kinase, that phosphorylates target proteins in the cell.

Patients with this disorder express symptoms such as seizures, recurrent headaches, deafness, and vomiting, but in extreme cases can cause anorexia (due to excessive vomiting), diabetes, and damage to motor skills, vision, and sharpness of mind (Chinnery and Hudson 145; Choi et al 354). MELAS is one of the more common mtDNA diseases caused by mutations, resulting in an abundance of studies concerning patients with MELAS. The mutation that causes MELAS is usually heteroplasmic – it can only affect a certain proportion of mitochondria in a cell – but, in rare cases, it can be homoplasmic, as Choi et al discovered in their

Lynch syndrome, previously known as hereditary nonpolyposis colorectal cancer (HNPCC) is a parental inherited condition that exposes a person to the risks of cancers, but most commonly colon cancer1-9. It is a heterozygous autosomal dominant genetic condition, which means that if only one parent carries the gene for Lynch syndrome (LS), then a 50 percent chance of passing on the mutation will be passed to each child1-9. LS is limited to families with a known pathogenic germline mutation2. A germline mutation is when mutations occur in the germ line, which is a group of cells that contribute to the improvement of gametes2,3,10. To find out how individuals are to contract this disease, the family medical history must be taken into account. Early

Introduction: CGRP belongs to calcitonin family of peptides which are of two types, α-CGRP (extensively studied) and β-CGRP. Alfa-CGRP is a 37-amino acid peptide that is produced from alternative splicing (1) of CGRP gene located on chromosome number 11. Beta-CGRP changes in 3 amino acids and encoded by a separate gene.(2)

Myomegalin, cAMP-specific 3’,5’-cyclic phosphodiesterase 4D(PDE4D) is important for cell signaling pathway to regulate the diffusion of cAMP and its ability to go to the PKA isoenzymes anchored to organelles (Bolger et al., 2003; Fleming et al., 2004).

Biology mainly concentrates on the study of life and any other factors that affect it positively or negatively. The study of biology is further sub-divided into sections and the most important being genetics that studies the genetically composition and effects to human life. For instance, gigantism which is an abnormal growth caused by the excess hormone growth at childhood before the bone plates closes. Though gigantism is rare, it is caused due to some factors among them; Noncancerous tumor of the pituitary gland, Neurofibromatosis, McCune-Albright Syndrome (MAS), Carney complex and Multiple Endocrine Neoplasia type 1(MEN-1). This abnormal growth occurs mainly before the closure of the bone growth plate. In any case the
