All of the following are usual elements of the syndrome:

- Short stature

- Abnormal calf bone shape (fibula)

- Unusual facial appearance

- Polycystic kidneys

- Abnormally long fibula

- Mild sunken chest

- Large corneas

- Inguinal hernia

- Umbilical hernia

The clinical presentation is variable but includes

- developmental and growth delay

- athletic muscular built

- skeletal anomalies

- joint stiffness

- characteristic facial appearance

- deafness

- variable cognitive deficits

- tracheal stenosis

- aortic stenosis

- pyloric stenosis

The facial abnormalities include:

- blepharophimosis (an abnormally narrow gap between the upper and lower eyelids)

- maxillary hypoplasia (underdevelopment of the upper jaw)

- prognathism (prominent lower jaw)

The skeletal abnormalities include:

- short stature

- square body shape

- broad ribs

- iliac hypoplasia

- brachydactyly

- flattened vertebrae

- thickened calvaria

Congenital heart disease and undescended testes have also been reported in association with this syndrome.

Symptoms are related to defects in connective tissue.

- Congenital anterior dislocation of the knees

- Dislocation of hips and shoulders

- Flattened facial appearance

- Prominent forehead

- Depressed nasal bridge

- Club foot

- Cervical kyphosis

The most common symptoms of Nicolaides–Baraitser syndrome are mild to severe developmental delays with absent or limited speech, seizures, short stature, sparse hair, typical facial characteristics, brachydactyly, and prominent finger joints and broad distal phalanges.

Common signs of Say–Meyer syndrome are trigonocephaly as well as head and neck symptoms. The head and neck symptoms come in the form of craniosynostosis affecting the metopic suture (the dense connective tissue structure that divides the two halves of the skull in children which usually fuse together by the age of six). Symptoms of Say–Meyer syndrome other than developmental delay and short stature include

- Intellectual disability.

- Low-set ears/posteriorly rotated ears

- Intellectual deficit as well as learning disability

- Intrauterine growth retardation (poor growth of a baby while it is in the mother's womb)

- Posterior fontanel

- Premature synostosis of the lambdoid suture (the fusion of the bones to the joint is premature)

- Narrow forehead

- Trigonocephaly (a frontal bone anomaly that is characterized by a premature fusion of the bones which gives the forehead a triangular shape)

- Hypotelorism or hypertelorism (reduced or increased width between the eyes)

- Craniosynostosis (when one or more seam-like junctions between two bones fuses by turning into bone. This changes the growth pattern of the skull)

- Low birth weight and height

The affected patients sometimes show a highly arched palate, clinodactyly (a defect in which toes or fingers are positioned abnormally) and ventricular septal defect (a heart defect that allows blood to pass directly from left to the right ventricle which is caused by an opening in the septum). Overall, Say–Meyer syndrome impairs growth, motor function, and mental state.

These symptoms were found in rare cases of Larsen syndrome.

- Cataracts

- Cleft palate

- Extra bones of wrist

- Malocclusion

- Microdontia and hypodontia

- Complete agenesis of anus

- uterus

- Bifid tongue

SHORT is an acronym for short stature, hyperextensibility of joints and/or inguinal hernia, ocular depression, rieger anomaly and teething delay.

Other characteristics common in SHORT syndrome are a triangular face, small chin with a dimple, a loss of fat under the skin (lipodystrophy), abnormal position of the ears, hearing loss and delayed speech.

Aneuploidy is often fatal, but in this case there is "X-inactivation" where the effect of the additional gene dosage due to the presence of extra X chromosomes is greatly reduced.

Much like Down syndrome, the mental effects of 49,XXXXY syndrome vary. Impaired speech and behavioral problems are typical. Those with 49,XXXXY syndrome tend to exhibit infantile secondary sex characteristics with sterility in adulthood and have some skeletal anomalies. Skeletal anomalies include:

- Genu valgum

- Pes cavus

- Fifth finger clinodactyly

The effects also include:

- Cleft palate

- Club feet

- Respiratory conditions

- Short or/and broad neck

- Low birth weight

- Hyperextensible joints

- Short stature

- Narrow shoulders

- Coarse features in older age

- Hypertelorism

- Epicanthal folds

- Prognathism

- Gynecomastia (rare)

- Muscular hypotonia

- Hypoplastic genitalia

- Cryptorchidism

- Congenital heart defects

- A very round face in infancy

Mild prenatal growth retardation

Moderate postnatal growth retardation

Mild to severe developmental delay

Severely impaired speech

Sparse hair

Progressive skin wrinkling

Thick, anteverted alae nasi

Long and broad philtrum

Large mouth

Thin upper and thick lower vermilion

Progressive prominence of distal phalanges

Progressive prominence of inter-phalangeal joints

Short metacarpals–metatarsals

The main characteristics of 49,XXXXX are intellectual disability, short stature and craniofacial abnormalities. Other physical traits include the following:

- Small head

- Ear abnormalities

- Widely spaced eyes with upward slanting palpebral fissures and epicanthal folds

- Short neck

- Broad nose with a depressed nasal bridge

- Hyperextension of the elbows

- Clinodactyly of the 5th finger

- Deformities of the feet

- Heart defects

SFMS affects the skeletal and nervous system. This syndrome's external signs would be an unusual facial appearance with their heads being slightly smaller and unusually shaped, a narrow face which is also called dolichocephaly, a large mouth with a drooping lower lip that are held open, protruding upper jaw, widely spaced upper front teeth, an underdeveloped chin, cleft palate and exotropied-slanted eyes with drooping eyelids.

Males who have SFMS have short stature and a thin body build. Also skin is lightly pigmented with multiple freckles. They may have scoliosis and chest abnormalities.

Affected boys have reduced muscle tone as infants and young children. X-rays sometimes show that their bones are underdeveloped and show characteristics of younger bones of children. Boys usually under the age of 10 have reduced muscle tone but later, patients with SFMS over the age of 10 have increased muscle tone and reflexes that cause spasticity. Their hands are short with unusual palm creases with short, shaped fingers and foot abnormalities are shortened and have fused toes and usually mild.

They have an absent of a spleen and the genitals may also show undescended testes ranging from mild to severe that leads to female gender assignment.

People who have SFMS have severe mental retardation. They are sometimes restless, behavior problems, seizures and severe delay in language development. They are self-absorbed with reduced ability to socialize with others around them. They also have psychomotor retardation which is the slowing-down of thoughts and a reduction of physical movements. They have cortical atrophy or degeneration of the brain's outer layer. Cortical atrophy is usually founded in older affected people.

Individuals affected by this disorder appear normal at birth. As the infant grows, however, their arms and legs do not develop properly and their body becomes thicker and shorter than normal The following are characteristics consistent with this condition:

- Brachydactyly syndrome

- Short stature

- Micromelia

- Skeletal dysplasia

- Abnormality of femur

Clinically and radiologically the disease is characterized by severe shortening of long bones (limb's both proximal and median segments are affected), aplasia or severe hypoplasia of ulna and fibula, thickened and curved radius and tibia. These anomalies can cause deformities of the hands and feet. Hypoplasia of the mandible can also be present.

An initial clinical report of this syndrome describes a 6-month-old boy with rhizomelic shortening, particularly in the arms, and protuberances over the lateral aspects of the clavicles. On radiographs the lateral third of the clavicles had a appearance resulting from an abnormal process or protuberance arising from the fusion center. His 22-year-old mother also had a height of 142 cm with an arm span of 136 cm and rhizomelic shortness of the limbs, maximal in the arms, and abnormalities of the acromioclavicular joints. Both the mother and the son had marked bilateral clinodactyly of the fifth fingers associated with hypoplastic middle phalanx.

Below are the common clinical features of those diagnosed with Floating–Harbor syndrome. Patients will show varying degrees of some or all FHS symptoms. Facial abnormalities are the most defining aspects of those diagnosed with this disease.

The most common symptoms are intellectual disability and recurrent seizures developing in infancy or early childhood. Typically the seizures are resistant to treatment with anti-epileptic drugs. Other symptoms may include:

- Microcephaly

- Lymphedema

- Facial abnormalities

- Immune deficiencies

- Abnormalities of retina

- Slow growth

- Short stature

Exner syndrome is sometimes misdiagnosed as interstitial cystitis in its very early stages, but once the fibula begins to malform, Exner is the only real diagnosis.

Langer mesomelic dysplasia (LMD) is a rare congenital disorder characterized by an altered bone formation that causes a severe short and disproportionate stature.

The differential diagnosis of broad thumbs includes Rubinstein-taybi syndrome, where they are a cardinal feature. FHS is also in the differential, which logically agrees with the thought that the disease is a result of a mutation in SRCAP, as this gene interacts with CBP.

Wallis–Zieff–Goldblatt syndrome is a rare condition characterized by inherited skeletal disorders manifested mainly as short stature and lateral clavicular defects. It is also known as Cleidorhizomelic syndrome.

People with Aarskog-Scott syndrome often have distinctive facial features, such as widely spaced eyes (hypertelorism), a small nose, a long area between the nose and mouth (philtrum), and a widow's peak hairline. They frequently have mild to moderate short stature during childhood, but their growth usually catches up with that of their peers during puberty. Hand abnormalities are common in this syndrome and include short fingers (brachydactyly), curved pinky fingers (fifth finger clinodactyly), webbing of the skin between some fingers (cutaneous syndactyly), and a single crease across the palm. Other abnormalities in people with Aarskog-Scott syndrome include heart defects and a split in the upper lip (cleft lip) with or without an opening in the roof of the mouth (cleft palate).

Most males with Aarskog-Scott syndrome have a shawl scrotum, in which the scrotum surrounds the penis instead of hanging below. Less often, they have undescended testes (cryptorchidism) or a soft out-pouching around the belly-button (umbilical hernia) or in the lower abdomen (inguinal hernia).

The intellectual development of people with Aarskog-Scott syndrome varies widely. Some may have mild learning and behavior problems, while others have normal intelligence. In rare cases, severe intellectual disability has been reported.

People with Renpenning's typically begin learning language at an ordinary pace, but by the age of 3–4 they experience a regression in mental and physical development, such as mild low muscle tone resulting in elongated faces and rapid loss in the normal growth of the head (microcephaly). Small testes and short stature are also known to commonly occur.

Stratton parker syndrome is a rare disorder characterized by short stature, wormian bones (extra cranial bones), and dextrocardia (displaced heart). Other symptoms include dermatoglyphics, tooth deformities or missing teeth, abnormal kidney development, shortened limbs, mental retardation, undescended testes or cryptorchidism, and anal atresia. The condition was first described by Stratton and Parker in 1989, and there have been only four reported cases worldwide. Two cases of the syndrome were reported by Gilles-Eric Seralini in 2010 after having been contacted in January 2009.

Alternative names include "Growth Hormone Deficiency with Wormian Bones, Cardiac Anomaly, and Brachycamptodactyly" and "Short stature wormian bones dextrocardia"

RAPADILINO syndrome is an autosomal recessive disorder characterized by:

- RA: radial ray defect

- PA: patellar aplasia, arched or cleft palate

- DI: diarrhea, dislocated joints

- LI: little size (short stature), limb malformation

- NO: nose slender and normal intelligence.

It is more prevalent in Finland than elsewhere in the world.

It has been associated with the gene RECQL4. This is also associated with Rothmund-Thomson syndrome and Baller-Gerold syndrome.

It is a disorder that is mostly characterized as developmental delay and short stature. Magnetic resonance imaging scans usually reveal that there is a decreased volume of white matter in the bilateral cerebral hemispheres, a brain stem that is smaller in size, and a thin corpus callosum (nerve fibers that connect the two hemispheres of the brain). The syndrome is one of the rare causes of short stature.
