This disorder is present at birth, however, it may not be understood until several years after birth. Acrodysostosis affects males and females in almost similar numbers. It is difficult to determine the frequency of acrodysostosis in the population as many cases of this disorder cannot be diagnosed properly.

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

Acrodysostosis also known as Arkless-Graham syndrome or Maroteaux-Malamut syndrome is a rare congenital malformation syndrome which involves shortening of the interphalangeal joints of the hands and feet, intellectual disability in approximately 90% of affected children, and peculiar facies. Other common abnormalities include short head (as measured front to back), small broad upturned nose with flat nasal bridge, protruding jaw, increased bone age, intrauterine growth retardation, juvenile arthritis and short stature. Further abnormalities of the skin, genitals, teeth, and skeleton may occur.

Most reported cases have been sporadic, but it has been suggested that the condition might be genetically related i.e. in an autosomal dominant mode of transmission. Both males and females are affected. The disorder has been associated with the older age of parents at the time of conception.

A PRKAR1A mutation has been identified in acrodysostosis with hormone resistance.

The aneuploidy is thought to be caused by problems occurring during meiosis, either in the mother or in both the mother and father. Successive nondisjunctions have been observed in the mother of at least one patient.

The features of the syndrome likely arise due to failure of X-inactivation and the presence of multiple X chromosomes from the same parent causing problems with parental imprinting. In theory, X-inactivation should occur and leave only one X chromosome active in each cell. However, failure of this process has been observed in one individual studied. The reason for this is thought to be the presence of an unusually large, and imbalanced, number of X chromosomes interfering with the process.

Genitopatellar Syndrome is an autosomal dominant inheritance where the mutation in the KAT6B causes the syndrome. The KAT6B gene is responsible for making an enzyme called histone acetyltransferase which functions in regulating and making of histone which are proteins that attach to DNA and give the chromosomes their shape. The function of histone acetyltransferase produced from KAT6B is unknown but it is considered as a regulator of early developments. There is little known about how the mutation in the KAT6B causes the syndrome but researchers suspects that the mutations occur near the end of the KAT6B gene and causes it to produce shortened acetyltransferase enzyme. The shortened enzyme alters the regulation of other genes. On the other hand, the mutation of KAT6B leading to the specific features of genitopatellar syndrome is still not surely proven.

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.

Zori–Stalker–Williams syndrome, also known as pectus excavatum, macrocephaly, short stature and dysplastic nails, is a rare autosomal dominant congenital disorder associated with a range of features such as pectus excavatum, macrocephaly and dysplastic nails, familial short stature, developmental delay and distinctive facies. Further signs are known to be associated with this syndrome.

The name originates from the researchers who first defined and noticed the syndrome and its clinical signs.

It is believed that the syndrome is inherited in an autosomal dominant pattern, though there has been no new research undertaken for this rare disease.

RIDDLE syndrome is a rare genetic syndrome. The name is an acronym for Radiosensitivity, ImmunoDeficiency Dysmorphic features and LEarning difficulties.

This condition is rare. Only four cases have been described up to 2017.

Trisomy 8 mosaicism affects wide areas of chromosome 8 containing many genes, and can thus be associated with a range of symptoms.

- Mosaic trisomy 8 has been reported in rare cases of Rothmund-Thomson syndrome, a genetic disorder associated with the DNA helicase RECQL4 on chromosome 8q24.3. The syndrome is "characterized by skin atrophy, telangiectasia, hyper- and hypopigmentation, congenital skeletal abnormalities, short stature, premature aging, and increased risk of malignant disease".

- Some individuals trisomic for chromosome 8 were deficient in production of coagulation factor VII due to a factor 7 regulation gene (F7R) mapped to 8p23.3-p23.1.

- Trisomy and other rearrangements of chromosome 8 have also been found in tricho–rhino–phalangeal syndrome.

- Small regions of chromosome 8 trisomy and monosomy are also created by recombinant chromosome 8 syndrome (San Luis Valley syndrome), causing anomalies associated with tetralogy of Fallot, which results from recombination between a typical chromosome 8 and one carrying a parental paracentric inversion.

- Trisomy is also found in some cases of chronic myeloid leukaemia, potentially as a result of karyotypic instability caused by the fusion gene.

Corneodermatosseous syndrome (also known as "CDO syndrome") is an autosomal dominant condition with onset in infancy, characterized by corneal dystrophy, photophobia, diffuse palmoplantar keratoderma, distal onycholysis, skeletal abnormalities, with brachydactyly, short stature, and medullary narrowing of digits.

SHORT syndrome is a medical condition in which affected individuals have multiple birth defects in different organ systems.

It was characterized in 1975.

Most cases are X-linked recessive but there may be as many as three types. As well as a classical X-linked form, there is another type where females are partially affected and another where females have full IFAP symptoms. The gene or genes causing this disease are not known.

Life expectancy for individuals with hypochondroplasia is normal; the maximum height is about 147 cm or 4.8 ft.

Genitopatellar syndrome is a rare disorder with characteristic craniofacial features, congenital flexion contractures of the lower limbs, absent or abnormal patellae, urogenital anomalies, and severe psychomotor retardation.

In 2012, it was shown that mutations in the gene KAT6B cause the syndrome.

IFAP syndrome is an extremely rare genetic syndrome. It is also known as Ichthyosis follicularis, alopecia, and photophobia syndrome or simply ichthyosis follicularis. It is extremely rare: there were only 10 known cases (all male) in 1998.

Watson syndrome is an autosomal dominant condition characterized by Lisch nodules of the ocular iris, axillary/inguinal freckling, pulmonary valvular stenosis, relative macrocephaly, short stature, and neurofibromas.

Watson syndrome is allelic to NF1, the same gene associated with neurofibromatosis type 1.

Katz Syndrome is a rare congenital disorder, presenting as a polymalformative syndrome characterized by enlarged viscera, hepatomegaly, diabetes, and skeletal anomalies that result in a short stature, cranial hyperostosis, and typical facial features. It is probably a variant of the autosomal recessive type of Craniometaphyseal Dysplasia.

Some characteristics of Abruzzo–Erickson syndrome include deafness, protruding ears, coloboma, a cleft palate or palatal rugosity, and short stature.

It was characterized in 1977.

It is caused by mutations in the SHOX gene found in the pseudoautosomal region PAR1 of the X and Y chromosomes, at band Xp22.33 or Yp11.32.

SHOX gene deletions have been identified as the major cause of Leri–Weill syndrome.

Leri–Weill dyschondrosteosis is characterized by mesomelic short stature, with bowing of the radius more so than the ulna in the forearms and bowing of the tibia while sparing the fibula.

Recurrence in siblings and apparent transmission from parent to child has long suggested a genetic defect with autosomal dominant inheritance and variable expression. Mutations in the Ras/mitogen activated protein kinase signaling pathways are known to be responsible for ~70% of NS cases.

A person with NS has up to a 50% chance of transmitting it to their offspring. The fact that an affected parent is not always identified for children with NS suggests several possibilities:

1. Manifestations could be so subtle as to go unrecognized (variable expressivity)

2. NS is heterogeneous, comprising more than one similar condition of differing causes, and some of these may not be inherited.

3. A high proportion of cases may represent new, sporadic mutations.

Heterozygous mutations in "NRAS", "HRAS", "BRAF", "SHOC2", "MAP2K1", "MAP2K2", and "CBL" have also been associated with a smaller percentage of NS and related phenotypes.

A condition known as "neurofibromatosis-Noonan syndrome" is associated with neurofibromin.

GMS syndrome is a syndrome characterised by goniodysgenesis, intellectual disability, and short stature.

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.

Mutations in the FGD1 gene are the only known genetic cause of Aarskog-Scott syndrome. The FGD1 gene provides instructions for making a protein that turns on (activates) another protein called Cdc42, which transmits signals that are important for various aspects of development before and after birth.

Mutations in the FGD1 gene lead to the production of an abnormally functioning protein. These mutations disrupt Cdc42 signaling, leading to the wide variety of abnormalities that occur in people with Aarskog-Scott syndrome.

Only about 20 percent of people with this disorder have identifiable mutations in the FGD1 gene. The cause of Aarskog-Scott syndrome in other affected individuals is unknown.

Berk–Tabatznik syndrome is a medical condition with an unknown cause that shows symptoms of short stature, congenital optic atrophy and brachytelephalangy. This condition is extremely rare with only two cases being found.
