While there is no cure for HPS, treatment for chronic hemorrhages associated with the disorder includes therapy with vitamin E and the antidiuretic dDAVP.

Treatment can include amoxicillin-clavulanic acid, intravenous fluid administration and paracetamol oral for pain relief. Other treatment varies based on the condition and extent of uropathy.

A preoperative pulmonology consultation is needed. The anesthesia team should

be aware that patients may have postoperative pulmonary complications as part

of the syndrome.

Preoperative hematology consultation is advisable prior to elective ocular

surgeries. Since patients with the syndrome have bleeding tendencies,

intraoperative, perioperative, and postoperative hemorrhages should be

prevented and treated. If platelet aggregation improves with desmopressin, it

may be administered in the preoperative period. However, sometimes

plasmapheresis is needed in the perioperative period.

Ophthalmologists should try to avoid retrobulbar blocks in patients with the

syndrome. Whenever possible, patients with HPS may benefit from general

endotracheal anesthesia. Phacoemulsification may help prevent intraoperative

and postoperative bleeding in patients with the syndrome. Prolonged bleeding

has been reported following strabismus surgery in patients with the syndrome.

Currently, purine replacement via S-adenosylmethionine (SAM) supplementation in people with Arts syndrome appears to improve their condition. This suggests that SAM supplementation can alleviate symptoms of PRPS1 deficient patients by replacing purine nucleotides and open new avenues of therapeutic intervention. Other non-clinical treatment options include educational programs tailored to their individual needs. Sensorineural hearing loss has been treated with cochlear implantation with good results. Ataxia and visual impairment from optic atrophy are treated in a routine manner. Routine immunizations against common childhood infections and annual influenza immunization can also help prevent any secondary infections from occurring.

Regular neuropsychological, audiologic, and ophthalmologic examinations are also recommended.

Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if the disease-causing mutation in the family is known.

In terms of treatment of oculocerebrorenal syndrome for those individuals who are affected by this condition includes the following:

- Glaucoma control (via medication)

- Nasogastric tube feeding

- Physical therapy

- Clomipramine

- Potassium citrate

Treatment for NPS varies depending on the symptoms observed.

- Perform screening for renal disease and glaucoma, surgery, intensive physiotherapy, or genetic counseling.

- ACE inhibitors are taken to treat proteinuria and hypertension in NPS patients.

- Dialysis and renal transplant.

- Physical therapy, bracing and analgesics for joint pain.

- Other surgery treatments such as patella realignment, joint replacement, and the cutting away of the head of radius.

Each child is different and it entirely depends on which sutures are fused and how it is affecting the child as to how it is treated. Some children have severe breathing issues due to shallow mid face and may require a tracheostomy. All should be treated at a specialist centre. Cranio bands are not used in the UK.

Surgery is typically used to prevent the closure of sutures of the skull from damaging the brain's development. Without surgery, blindness and mental retardation are typical outcomes. Craniofacial surgery is a discipline of both plastic surgery and oral and maxillofacial surgery (OMFS) . To move the orbits forward, craniofacial surgeons expose the skull and orbits and reshape the bone. To treat the midface deficiency, craniofacial surgeons can move the lower orbit and midface bones forward. For jaw surgery, either plastic surgeons or OMFS surgeons can perform these operations.

Crouzon patients tend to have multiple sutures involved, most specifically bilateral coronal craniosynostoses, and either open vault surgery or strip craniectomy (if child is under 6 months) can be performed. In the later scenario, a helmet is worn for several months following surgery.

Once treated for the cranial vault symptoms, Crouzon patients generally go on to live a normal lifespan.

Treatment is usually supportive treatment, that is, treatment to reduce any symptoms rather than to cure the condition.

- Enucleation of the odontogenic cysts can help, but new lesions, infections and jaw deformity are usually a result.

- The severity of the basal-cell carcinoma determines the prognosis for most patients. BCCs rarely cause gross disfigurement, disability or death .

- Genetic counseling

Regular administration of exogenous granulocyte colony-stimulating factor (filgrastim) clinically improves neutrophil counts and immune function and is the mainstay of therapy, although this may increase risk for myelofibrosis and acute myeloid leukemia in the long term.

Over 90% of SCN responds to treatment with granulocyte colony-stimulating factor (filgrastim), which has significantly improved survival.

Since tetrasomy 9p is not usually inherited, the risk of a couple having a second child with the disorder is minimal. While patients often do not survive to reproductive age, those who do may or may not be fertile. The risk of a patient's child inheriting the disorder is largely dependent on the details of the individual's case.

Platelet storage pool deficiency has no treatment however management consists of antifibrinolytic medications if the individual has unusual bleeding event, additionally caution should be taken with usage of NSAIDS

In 2010, the case of a man with unexplained erythrocytosis and perinephric fluid collection as main features was described in the Case Records of the Massachusetts General Hospital. As a consequence two strikingly similar cases were identified and a review of the literature revealed three more patients with similar characteristics.

As of December 2014, a total of 9 patients worldwide with the TEMPI syndrome have been identified (D.B.Sykes, Personal Communication).

In terms of their therapy:

- Untreated: 2 patients

- Velcade alone: 5 patients

- Immediate autologous transplant: 1 patient

- Velcade followed by Velcade/Lenalidomide followed by autologous transplant: 1 patient

Urofacial (Ochoa) syndrome received the Ochoa name because of the first person to describe it back in 1987, Bernardo Ochoa.

Usually the hemangioma requires medical therapy. The child may need other therapies, depending on what other organs or structures are involved.

A 2007 study followed 112 individuals for a mean of 12 years (mean age 25.3, range 12–71). No patient died during follow-up, but several required medical interventions. The mean final heights were 167 and 153 cm for men and women, respectively, which is approximately 2 standard deviations below normal.

The treatment of primary immunodeficiencies depends foremost on the nature of the abnormality. Somatic treatment of primarily genetic defects is in its infancy. Most treatment is therefore passive and palliative, and falls into two modalities: managing infections and boosting the immune system.

Reduction of exposure to pathogens may be recommended, and in many situations prophylactic antibiotics or antivirals may be advised.

In the case of humoral immune deficiency, immunoglobulin replacement therapy in the form of intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (SCIG) may be available.

In cases of autoimmune disorders, immunosuppression therapies like corticosteroids may be prescribed.

Though the outcome for individuals with either form of the tetrasomy is highly variable, mosaic individuals consistently experience a more favourable outcome than those with the non-mosaic form. Some affected infants die shortly after birth, particularly those with the non-mosaic tetrasomy. Many patients do not survive to reproductive age, while others are able to function relatively normally in a school or workplace setting. Early diagnosis and intervention has been shown to have a strong positive influence on the prognosis.

3q29 microdeletion syndrome is a rare genetic disorder resulting from the deletion of a segment of chromosome 3. This syndrome was first described in 2005.

MORM syndrome is an autosomal recessive congenital disorder This means that the disorder is present from birth and is likely the result of both healthy parents passing on a defective gene, associated with MORM syndrome, to their offspring. The disorder is not dependent on sex of the offspring, both male and female offspring are equally likely to inherit the disorder. The term MORM is used to describe the characteristics associated with the disorder which include mental retardation, truncal obesity, retinal dystrophy, and micropenis". The disorder shares similar characteristics with Bardet-Biedl syndrome and Cohen syndrome, both of which are autosomal recessive genetic disorders. MORM syndrome can be distinguished from the above disorders because symptoms appear at a young age.

The syndrome is caused by a mutation in the INPP5E gene which can be located on chromosome 9 in humans. Further mapping resulted in the identification of a MORM syndrome locus on chromosome 9q34.3 between the genetic markers D9S158 and D9S905.

Bone marrow transplant may be possible for Severe Combined Immune Deficiency and other severe immunodeficiences.

Virus-specific T-Lymphocytes (VST) therapy is used for patients who have received hematopoietic stem cell transplantation that has proven to be unsuccessful. It is a treatment that has been effective in preventing and treating viral infections after HSCT. VST therapy uses active donor T-cells that are isolated from alloreactive T-cells which have proven immunity against one or more viruses. Such donor T-cells often cause acute graft-versus-host disease (GVHD), a subject of ongoing investigation. VSTs have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens. This is carried out by using donor-derived antigen-presenting cells. These new methods have reduced culture time to 10–12 days by using specific cytokines from adult donors or virus-naive cord blood. This treatment is far quicker and with a substantially higher success rate than the 3–6 months it takes to carry out HSCT on a patient diagnosed with a primary immunodeficiency. T-lymphocyte therapies are still in the experimental stage; few are even in clinical trials, none have been FDA approved, and availability in clinical practice may be years or even a decade or more away.

Chloramphenicol therapy should be stopped immediately. Exchange transfusion may be required to remove the drug. Sometimes, phenobarbital (UGT induction) is used.

The condition can be prevented by using chloramphenicol at the recommended doses and monitoring blood levels, or alternatively, third generation cephalosporins can be effectively substituted for the drug, without the associated toxicity.

PHACE syndrome needs to be managed by a multidisciplinary team of experts. Additional specialties such as cardiology, ophthalmology, neurology, and neurosurgery may need to be involved. The team of experts pay close attention to how these children develop throughout the school age period.

PHACE Syndrome Handbook - Dr. Beth Drolet

In 2013, the PHACE Syndrome Community was formed. The non-profit entity was developed to raise awareness about the condition, support patients and families of those with the condition and raise money for research into causes and treatment.

Fraser syndrome (also known as Meyer-Schwickerath's syndrome, Fraser-François syndrome, or Ullrich-Feichtiger syndrome) is an autosomal recessive congenital disorder. Fraser syndrome is named for the geneticist George R. Fraser, who first described the syndrome in 1962.

Smith Martin Dodd syndrome is a very rare genetic disorder first described by Smith et al. in 1994. It is characterized by small eyes, a diaphragmatic hernia, and Tetralogy of Fallot, a congenital heart defect. The only known case is of a 9-year-old boy with several congenital anomalies including a diaphragmatic hernia, microphthalmia, and Tetralogy of Fallot. It was found that the boy had a reciprocal translocation t(1;15)(q41;q21.2). A congenital diaphragmatic hernia is consistent with chromosome 1q41-q42 deletion syndrome, and the report by Smith et al. suggested that genes involved in the translocation may be important for the development of morphological characteristics, especially those of the eye or heart.
