Introduction

The Lesch-Nyhan syndrome (LNS), was found by Michael Lesch and William Nyhan and has provided the first detailed clinical description of Lesch-Nyhan disease in 1964, is a rare inherited disorder transmitted as a sex-linked trait and caused by a deficiency of an enzyme of purine metabolism: hypoxanthine-guanine phosphoribosyltransferase (HGPRT). (1)
Epidemiology
The lesch-Nyhan disease, it is a rare genetic disorder that can be transmitted at birth. Estimate show that at birth it affect 1/380000 and 1/235000 live births. The lesch Nyhan syndrome is an x-linked recessive disease. The gene mutation or a mutant …show more content…

The term Lesch-Nyhan variants has been introduced to include patients with HPRT-related gout and some degree of neurological involvement, but without the complete Lesch-Nyhan syndrome. (7)
Overproduction of uric acid: one of the first and most common symptoms of this disease is the presence of sand- like crystals or orange crystals of uric acid in the diapers of an affected infant. This development of uric acid crystals or stone is as a result of the overproduction of uric acid in the body. These orange grainy material crystals may coalesce to form either multiple tinny stones like in gravel forms, or may appear in distinct large stones that might be much difficult to pass. These large stones gravel and crystals, like to form in three main areas of the body.
1. It affects the area of the bone joint, especially those of the fingers and toes. When these occur, the crystals cause irritation of the joints between the bones.

The characteristic phenotypic occurrences that are distinct to the disorder: poor muscle tone, stout neck, flat face, small head, mouth, and ears, eyes slanting upwardly, Brushfield spots, and stout fingers and

Of course, the condition will most likely involve a heart problem, which is discovered at birth, along with a webbed neck, chest deformities, many birth marks, also known as café-au-lait spots, and a short stature. The features of this syndrome are not fully known, considering the fact that there are numerous characteristics and no two infected individuals have the same exact features. Like in most other disease cases, there are lists of more minor symptoms that can occur in an individual. In infants and newborns, feeding problems are present, due to a poor sucking reflex. Behavioral problems and developmental delays can occur, which causes the individual to achieve milestones slower, such as sitting and walking.

There is a spectrum of severity ranging from no clinical symptoms, to simple febrile seizures, and extending to Dravet syndrome, which is the most severe. Mutations of the SCN1A gene cause 79% of diagnosed cases of Dravet syndrome. Frequently referred to as a sodium channelopathy, this intractable (uncontrollable) epilepsy is characterized by unilateral (one-sided) clonic or tonic clonic (grand mal) seizures that may be prolonged progress to status epilepticus. After years of trying to find the cause they were running out of solutions and finally running out of doctors.

The gene involved is recessive: the disease occurs only when homozygous (two copies of the gene are present); heterozygous (carrier) animals show no symptoms, but are likely to be much more widespread in the population than affected animals.[4]Today, the breed is found mainly in English-speaking countries, and Southern South America. The main countries are: Argentina, Australia, Canada, New Zealand,

The infant may develop temporary muscle weakness and associated findings (i.e., transient neonatal myasthenia gravis). The passage of anti-acetylcholine receptor antibodies through the placenta to the unborn child during pregnancy may cause this condition to the infant. Some of the myasthenia gravis is inherited as an autosomal recessive, or more rarely, an autosomal dominant condition is described as congenital myasthenia gravis. The individual that inherits two copies of an abnormal gen for the same trait from each parent, the individual will have recessive genetic disorders. If the individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease but usually will not show symptoms.

Gout Case Study

868 Words | 4 Pages

Gout is the most common inflammatory type of arthritis affecting adults. The clinical syndrome of gout arises from deposition of urate crystals in joints,where they cause an inflammatory response, and in soft tissues where they do not. Crystal deposition occurs when serum becomes saturated with urate,the final breakdown product of purine metabolism. It is characterized by chronic hyperuricemia which is defined as serum urate levels above 6.8mg/dl,the level above which the physiological saturation threshold is exceeded. Typically gout produces an acute monoarthritis of rapid onset,often waking patients from sleep.
