If the syndrome was found in the family, chances of a second child with the syndrome are 50%, because the syndrome is autosomal dominant. The effect of the syndrome on the child cannot be predictedThe syndrome can be detected with fluorescence in situ hybridization. For parents with a child with the syndrome, it is advisable to consult a physician before another pregnancy. Management
Treatment of cause: Due to the genetic cause, no treatment of the cause is possible.Treatment of manifestations: routine treatment of ophthalmologic, cardiac, and neurologic findings; speech, occupational, and physical therapies as appropriate; specialized learning programs to meet individual needs; antiepileptic drugs or antipsychotic medications as needed.Surveillance: routine pediatric care; routine developmental assessments; monitoring of specific identified medical issues. Prevalence
As of October 2012, Unique, an international rare chromosome disorder group and registry, has 64 genetically confirmed cases of this deletion worldwide. Research
On several locations in the world people are studying on the subject of 1q21.1 deletion syndrome. The syndrome was identified for the first time with people with heart abnormalities. The syndrome has later been found in patients with schizophrenia. Research is done on patients with a symptom of the syndrome, to find more patients with the syndrome.There may be a relation between autism and schizophrenia. Literature shows that nine locations have been found on the DNA where the syndromes related to autism or schizophrenia can be found, the so-called "hotspots": 1q21.1, 3q29, 15q13.3, 16p11.2, 16p13.1, 16q21, 17p12, 21q11.2 and 21q13.3.
Additionally, continuing daily zinc supplementation for ten to fourteen days makes diarrhea less likely to recur in the next two to three months.Malnourished children also need both potassium and magnesium. Within two to three hours of starting rehydration, children should be encouraged to take food, particularly foods rich in potassium like bananas, green coconut water, and unsweetened fresh fruit juice. Along with continued eating, many homemade products can also help restore normal electrolyte levels. For example, early during the course of a childs diarrhea, it can be beneficial to provide cereal water (salted or unsalted) or vegetable broth (salted or unsalted). If available, vitamin A, potassium, magnesium, and zinc supplements should be added, along with other vitamins and minerals.Giving base (as in Ringers lactate) to treat acidosis without simultaneously supplementing potassium worsens low blood potassium. Treating diarrhea
Preventing dehydration
Food and drink can help prevent dehydration in malnourished people with diarrhea. Eating (or breastfeeding, among infants) should resume as soon as possible. Sugary beverages like soft drinks, fruit juices, and sweetened teas are not recommended as they may worsen diarrhea.Malnourished people with diarrhea (especially children) should be encouraged to drink fluids; the best choices are fluids with modest amounts of sugar and salt, like vegetable broth or salted rice water. If clean water is available, they should be encouraged to drink that too. Malnourished people should be allowed to drink as much as they want, unless signs of swelling emerge. Babies can be given small amounts of fluids via an eyedropper or a syringe without the needle.
