Prader-Willi (PWS) syndrome is a rare genetic disease gone seven genes as regards the fifteenth paternal chromosome are absent or operational abnormally. This sickness was first described in 1956 by scholars Andrea Prader and Henry Willi.
SPW occurs in one out of 25000-100000 births. It is important to recall that the genetic material which influences the have an effect on ahead of this disease belongs to the father. The phenomenon of imprinting in the place of fifteenth chromosome takes place. It means that some genes of this place have lonesome one copy of gene that functions normally by means of imprinting. So that though most of people have one lively copy of these genes people considering PWS don’t have this copy at all.

Symptoms of the illness
The presence of the following symptoms gives the possibility to make a preliminary diagnosis even though not each and every one of one of them occur:

Violation of the to your liking sufficient sexual build taking place;
The feel of stretch marks;
Delay in the loan of motor skills.
Prader-Willi syndrome is often connected following an anomalous accretion of the appetite which often leads to morbid obesity. Today there are no true reasons which could explain the space of this syndrome, even though genetic disorders in the fifteenth chromosome violate customary supple of hypothalamus.
Hypothalamus regulates the basic processes of the organism including appetite. Its impairment can become a real gloss of quality of obesity.
Compulsive behavior (which is usually expressed by increased shakeup and skin picking), hallucinations, paranoia and depression are the main disorders of patients as soon as PWS. Psychiatric problems are the most frequent cause of their hospitalization.
Diagnostics
Today there flesh and blood not quite 400000 people together in the middle of PWS. As it was already mentioned this illness is usually characterized by hypotension, unexpected stature, obesity and psychic problems. In complement to this, people who vacillate from PWS have a outrage mental lack.
If to diagnose this disease at an to come stage and to begin the right treatment plus the prognosis becomes more optimistic. PWS as adeptly as autism has a wide range of symptoms. The course of the disease varies from measures to feat and can have either daub form or discordant one, which can clarify during the lifetime. PWS affects various organs and systems. Very often it becomes hard for doctors to diagnose this syndrome because of the fact that they know nothing more or less it. That is why PWS is often mortified gone Down’ syndrome.
