Depending on the altered enzyme, there are several types of disorder, each with different Porphyria symptoms. Introduction Porphyrias are a rare group of disorders caused by an alteration in one of the enzymes responsible for the biosynthesis of ...http://www.brighthub.com/science/genetics/articles/56249.aspxTue, 17 Nov 2009 06:53:30 GMTb133e95a-c263-4882-8f2a-b24547eff78e:56249dgemmellaroPoland syndrome is a rare birth condition characterized by the absence of the chest muscle on one side of the body and by webbing of the fingers. The cause of this condition is unknown and treatment usually consists of muscle and breast reconstruction, as well as separation of the joined fingers. Poland Syndrome Poland syndrome is a rare birth cond...http://www.brighthub.com/science/genetics/articles/52415.aspxWed, 14 Oct 2009 13:34:03 GMTb133e95a-c263-4882-8f2a-b24547eff78e:52415dgemmellaroSince viruses do not have a cellular structure, they cannot replicate through the process of cell division. But we know that populations of viruses grow. How do they do this? Through either the lytic cycle or the lysogenic cycle, or sometimes both. This article will explore the lytic cycle. Introduction The lytic and lysogenic cycle differ main...http://www.brighthub.com/science/genetics/articles/52286.aspxTue, 13 Oct 2009 11:53:28 GMTb133e95a-c263-4882-8f2a-b24547eff78e:52286dgemmellaroVon Hippel-Lindau syndrome, known as VHL, is an inherited autosomal dominant disease that causes tumors throughout various regions of the body. The symptoms and the characteristics of VHL are actually quite different from patient to patient, making the diagnosis of this disease often problematic. The Mutation at the Heart of the Disease The cause o...http://www.brighthub.com/science/genetics/articles/50413.aspxSun, 27 Sep 2009 10:59:54 GMTb133e95a-c263-4882-8f2a-b24547eff78e:50413dgemmellaroTuberculosis is a disease that has accompanied humans throughout most of history, at times decimating large groups of people. Read on to learn the history of tuberculosis and who discovered the cause. What is tuberculosis? Tuberculosis is a disease that usually affects the respiratory system, but it can also affect the gastro-intestinal system,...http://www.brighthub.com/science/genetics/articles/50412.aspxSun, 27 Sep 2009 10:25:57 GMTb133e95a-c263-4882-8f2a-b24547eff78e:50412dgemmellaroThe bacterium Vibrio cholerae is the microorganism that causes the disease known as cholera. The isolation of the bacterium was an important discovery in the history of medicine. Who discovered cholera? Read on to find out that the answer to that question is not as simple as you would think. Introduction Cholera is an infectious, at times deadl...http://www.brighthub.com/science/genetics/articles/49582.aspxMon, 21 Sep 2009 12:02:16 GMTb133e95a-c263-4882-8f2a-b24547eff78e:49582dgemmellaroDandy-Walker Syndrome is an unpleasant condition that involves the malformation of areas of the brain. While the causes of the disorder are still not completely known, researchers seem to be closing in on what seems to be a genetic component of the disease. Introduction What is Dandy-Walker Syndrome? It is a congenital malformation that affects the...http://www.brighthub.com/science/genetics/articles/49585.aspxMon, 21 Sep 2009 12:40:58 GMTb133e95a-c263-4882-8f2a-b24547eff78e:49585dgemmellaroOften caused by a genetic defect, an acoustic neuroma is a benign tumor arising from a certain group of nerve cells. This article will explore acoustic neuroma symptoms and the genetic basis of the disease. Introduction An acoustic neuroma is a type of benign tumor that develops inside the inner ear and affects the nerves responsible for hearing an...http://www.brighthub.com/science/genetics/articles/49576.aspxMon, 21 Sep 2009 10:43:41 GMTb133e95a-c263-4882-8f2a-b24547eff78e:49576dgemmellaroThis article discusses the condition known as alopecia areata and how genes are involved in what many researchers believe to be an autoimmune disorder. Introduction What is alopecia areata? Well, technically, it is a pathological condition characterized mainly by the loss of hair in a clearly delimited area. While the most common and clearly visibl...http://www.brighthub.com/science/genetics/articles/47643.aspxMon, 31 Aug 2009 05:28:56 GMTb133e95a-c263-4882-8f2a-b24547eff78e:47643dgemmellaroDue to the common ancestry of all species, many diseases, (especially genetic) found in humans can be found in other organisms. For example, Cushing’s disease, an endocrine disease that affects people, can also be found in a variety of other animals, including horses. Introduction Cushing’s disease in horses, though similar in name to...
