Some people may have some mental slowness, but children with this condition often have good social skills. Some males may have problems with fertility.

Similar to all genetic diseases Aarskog–Scott syndrome cannot be cured, although numerous treatments exist to increase the quality of life.

Surgery may be required to correct some of the anomalies, and orthodontic treatment may be used to correct some of the facial abnormalities. Trials of growth hormone have been effective to treat short stature in this disorder.

A number of features found with Nasodigitoacoustic syndrome can be managed or treated. Sensorineural hearing loss in humans may be caused by a loss of hair cells (sensory receptors in the inner ear that are associated with hearing). This can be hereditary and/or within a syndrome, as is the case with nasodigitoacoustic syndrome, or attributed to infections such as viruses. For the management of sensorineural hearing loss, hearing aids have been used. Treatments, depending upon the cause and severity, may include a pharmacological approach (i.e., the use of certain steroids), or surgical intervention, like a cochlear implant.

Pulmonary, or pulmonic stenosis is an often congenital narrowing of the pulmonary valve; it can be present in nasodigitoacoustic-affected infants. Treatment of this cardiac abnormality can require surgery, or non-surgical procedures like balloon valvuloplasty (widening the valve with a balloon catheter).

After the first discovery and description of Marshall–Smith syndrome in 1971, research to this rare syndrome has been carried out.

Many of the congenital malformations found with Malpuech syndrome can be corrected surgically. These include cleft lip and palate, omphalocele, urogenital and craniofacial abnormalities, skeletal deformities such as a caudal appendage or scoliosis, and hernias of the umbillicus. The primary area of concern for these procedures applied to a neonate with congenital disorders including Malpuech syndrome regards the logistics of anesthesia. Methods like tracheal intubation for management of the airway during general anesthesia can be hampered by the even smaller, or maldeveloped mouth of the infant. For regional anesthesia, methods like spinal blocking are more difficult where scoliosis is present. In a 2010 report by Kiernan et al., a four-year-old girl with Malpuech syndrome was being prepared for an unrelated tonsillectomy and adenoidectomy. While undergoing intubation, insertion of a laryngoscope, needed to identify the airway for the placement of the endotracheal tube, was made troublesome by the presence of micrognathia attributed to the syndrome. After replacement with a laryngoscope of adjusted size, intubation proceeded normally. Successful general anesthesia followed.

A rare follow-up of a male with Malpuech syndrome was presented by Priolo et al. (2007). Born at term from an uneventful pregnancy and delivery, the infant underwent a surgical repair of a cleft lip and palate. No problems were reported with the procedure. A heart abnormality, atrial septal defect, was also apparent but required no intervention. At age three years, mental retardation, hyperactivity and obsessive compulsive disorder were diagnosed; hearing impairment was diagnosed at age six, managed with the use of hearing aids. Over the course of the decade that followed, a number of psychiatric evaluations were performed. At age 14, he exhibited a fear of physical contact; at age 15, he experienced a severe psychotic episode, characterized by agitation and a loss of sociosexual inhibition. This array of symptoms were treated pharmocologically (with prescription medications). He maintained a low level of mental deficiency by age 17, with moments of compulsive echolalia.

The RASopathies are developmental syndromes caused by germline mutations (or in rare cases by somatic mosaicism) in genes that alter the Ras subfamily and mitogen-activated protein kinases that control signal transduction, including:

- Capillary malformation-AV malformation syndrome

- Autoimmune lymphoproliferative syndrome

- Cardiofaciocutaneous syndrome

- Hereditary gingival fibromatosis type 1

- Neurofibromatosis type 1

- Noonan syndrome

- Costello syndrome, Noonan-like

- Legius syndrome, Noonan-like

- Noonan syndrome with multiple lentigines, formerly called LEOPARD syndrome, Noonan-like

While only a few adults have been reported with 2q37 microdeletion syndrome, it is predicted that this number will rise as various research studies continue to demonstrate that most with the disorder do not have a shortened life span.

Currently there is no specific treatment for this condition. Management is supportive.

Renal dysplasia-limb defects syndrome (RL syndrome), also known as Ulbright–Hodes syndrome, is a very rare autosomal recessive congenital disorder. It has been described in three infants, all of whom died shortly after birth.

RL syndrome is characterized by renal dysplasia, growth retardation, phocomelia or mesomelia, radiohumeral fusion (joining of radius and humerus), rib abnormalities, anomalies of the external genitalia and potter-like facies among many others.

Pashayan syndrome also known as Pashayan–Prozansky Syndrome, and blepharo-naso-facial syndrome is a rare syndrome. Facial abnormalities characterise this syndrome as well as malformation of extremities. Specific characteristics would be a bulky, flattened nose, where the face has a mask like appearance and the ears are also malformed.

A subset of Pashayan syndrome has also been described, known as "cerebrofacioarticular syndrome", "Van Maldergem syndrome'" or "Van Maldergem–Wetzburger–Verloes syndrome". Similar symptoms are noted in these cases as in Pashayan syndrome.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

Marshall–Smith syndrome is not to be confused with:

- Marshall syndrome (aka.Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA syndrome, see also: Periodic fever syndrome)

- Sotos (like) syndrome

- Weaver-Smith syndrome (WSS)

Hystrix-like ichthyosis–deafness syndrome (also known as "HID syndrome") is a cutaneous condition characterized by a keratoderma.

Nablus mask-like facial syndrome is a microdeletion syndrome triggered by a deletion at chromosome 8 q22.1 that causes a mask-like facial appearance in those affected.

It is characterized by a narrowing of the eyes, tight, glistening facial skin, and a flat, broad nose. Other features of the syndrome include malformed ears, unusual hair patterns on the scalp, bent fingers and toes and joint deformities in the hands and feet, unusual teeth, mild developmental delay, cryptorchidism, and a generally happy disposition. It is a rare genetic disorder by inheritance found in Palestinian people named after Nablus city in the West Bank. It is part of many new genetic disorders of newborns that is increasing exponentially in Arabs in recent years as reported by Centre for Arab Genomic Studies in Dubai.

Albinism–deafness syndrome (also known as "Woolf syndrome" and "Ziprkowski–Margolis syndrome") is a condition characterized by congenital neural deafness and a severe or extreme piebald-like phenotype with extensive areas of hypopigmentation.

A locus at Xq26.3-q27.I has been suggested.

It has been suggested that it is a form of Waardenburg syndrome type II.

HIES was first described by Davis et al. in 1966 in two girls with red hair, chronic dermatitis, and recurrent staphylococcal abscesses and pneumonias. They named the disease after the biblical figure Job, whose body was covered with boils by Satan. In 1972, Buckley et al. described two boys with similar symptoms as well as coarse facies, eosinophilia, and elevated serum IgE levels. These two syndromes are thought to be the same and are under the broad category of HIES.

Males are twice as likely as females to have this characteristic, and it tends to run in families. In its non-symptomatic form, it is more common among Asians and Native Americans than among other populations, and in some families there is a tendency to inherit the condition unilaterally, that is, on one hand only.

The presence of a single transverse palmar crease can be, but is not always, a symptom associated with abnormal medical conditions, such as fetal alcohol syndrome, or with genetic chromosomal abnormalities, including Down Syndrome (chromosome 21), cri du chat syndrome (chromosome 5), Klinefelter syndrome, Wolf-Hirschhorn Syndrome, Noonan syndrome (chromosome 12), Patau syndrome (chromosome 13), IDIC 15/Dup15q (chromosome 15), Edward's syndrome (chromosome 18), and Aarskog-Scott syndrome (X-linked recessive), or autosomal recessive disorder, such as Leaukocyte adhesion deficiency-2 (LAD2). A unilateral single palmar crease was also reported in a case of chromosome 9 mutation causing Nevoid basal cell carcinoma syndrome and Robinow syndrome. It is also sometimes found on the hand of the affected side of patients with Poland Syndrome, and craniosynostosis.

Malpuech facial clefting syndrome, also called Malpuech syndrome or Gypsy type facial clefting syndrome, is a rare congenital syndrome. It is characterized by facial clefting (any type of cleft in the bones and tissues of the face, including a cleft lip and palate), a appendage (a "human tail"), growth deficiency, intellectual and developmental disability, and abnormalities of the renal system (kidneys) and the male genitalia. Abnormalities of the heart, and other skeletal malformations may also be present. The syndrome was initially described by Guilliaume Malpuech and associates in 1983. It is thought to be genetically related to Juberg-Hayward syndrome. Malpuech syndrome has also been considered as part of a spectrum of congenital genetic disorders associated with similar facial, urogenital and skeletal anomalies. Termed "3MC syndrome", this proposed spectrum includes Malpuech, Michels and Mingarelli-Carnevale (OSA) syndromes. Mutations in the "COLLEC11" and "MASP1" genes are believed to be a cause of these syndromes. The incidence of Malpuech syndrome is unknown. The pattern of inheritance is autosomal recessive, which means a defective (mutated) gene associated with the syndrome is located on an autosome, and the syndrome occurs when two copies of this defective gene are inherited.

The syndrome was initially described in 1973 by James A. Keipert and associates. They reported of two brothers with broad distal phalanges, sensorineural hearing loss, and facial features consistent with what would become known as Keipert or "nasodigitoacoustic" syndrome. Although no specific rate of incidence has been determined, the syndrome is considered a rare disease by both the Office of Rare Diseases (ORDR) at the National Institutes of Health, and Orphanet. This suggests, respectively, that Nasodigitoacoustic syndrome affects less than 200,000 people in the U.S., or affects no greater than 1 per 2,000 people in Europe.

Therapy can help developmental delays, as well as physiotherapy for the low muscle tone. Exercise and healthy eating can reduce weight gain. Treatments are available for seizures, eczema, asthma, infections, and certain bodily ailments.

Proteus-like syndrome (PLS) is a condition similar to Proteus syndrome, but with an uncertain cause.

Somatic mutations in the PIK3CA have been identified as a cause of CLOVES syndrome. PIK3CA is a protein involved in the PI3K-AKT signalling pathway. Mutations in other parts of this pathway cause other overgrowth syndromes including proteus syndrome and hemimegaencephaly.

Multiple hamartoma syndrome is a syndrome characterized by more than one hamartoma.

It is sometimes equated with Cowden syndrome. However, MeSH also includes Bannayan–Zonana syndrome (that is, Bannayan–Riley–Ruvalcaba syndrome) and Lhermitte–Duclos disease under this description. Some articles include Cowden syndrome, Bannayan–Riley–Ruvalcaba syndrome, and at least some forms of Proteus syndrome and Proteus-like syndrome under the umbrella term PTEN hamartoma tumor syndromes (PHTS).

There has been no treatment discovered for Jacobsen Syndrome until now but the Symptoms can be treated. 56% of children with Jacobsen Syndrome have congenital heart problems to keep them in check a baseline evaluation can be made by a paediatric cardiologist by carrying out an electrocardiogram or echocardiogram. Any problems that are found can be treated then.

Almost all affected children are born with a bleeding disorder, monthly CBT may help ease the problem. Consecutively Platelet transfusion and ddAVP can be carried out. Medication that interferes with platelet count should be avoided and oral contraceptive therapy may be considered for women with heavy bleeding during menses.

Children affected with Jacobsen Syndrome have severe to Moderate intellectual disabilities and cognitive impairment. An evaluation by a neuropsychologist or a behaviour specialist like a Psychiatrist or Psychologist can be performed, including brain imaging like MRI or ERP. Then as deemed appropriate intervention programs can be carried through. Music therapy is very beneficial for language development. According to the age, befitting vision and hearing test can aid in fixing problems related cognition. For problems related to behaviour like ADHD, medication or therapy would be required but a combination of both is more effective. An ophthalmologist should be consulted to treat the eye defects. Play and interactive games encourage the child to speak. Habilitiation in children should begin at an early age. A habilitation team includes professionals with special expertise in how disability affects everyday life, health and development. The entire family is supported to help the affected children and their families adjust better.
