Quick Answer: What is Robinow syndrome?

Robinow syndrome is a very rare genetic disorder that affects the development of the skeleton and other parts of the body. It can cause short limbs, fingers and toes, a curved spine, rib problems, distinctive facial features, genital abnormalities and developmental delays. It is caused by a genetic mutation, and diagnosis is based on physical signs confirmed with genetic testing. [1]

What the research says

  • Gum overgrowth is a near-constant feature, while other facial features vary. In a multidisciplinary evaluation of 13 people with dominant or recessive Robinow syndrome, gingival hyperplasia was nearly ubiquitous. Orbital hypertelorism, a short nose with flared nares, a triangular mouth with a long philtrum, cleft palate, macrocephaly, and frontal bossing were seen in some, but not all, individuals (Conlon et al., Am J Med Genet A, 2021). [2]

  • Genital differences are common in males and can affect self-perception. In 9 males examined by urologists (average age 19.9 years), penile transposition was found in all 9, buried penis in 7 of 9, and undescended testicles in 4 of 10. Of those who answered a pilot questionnaire, 78% reported diminished sexuality, sexual function, and self-perception, and the authors called for studies of interventions to address this. Genital findings did not correlate with the specific gene involved (Gerber et al., Am J Med Genet A, 2021). [3]

What Is Robinow Syndrome?

Robinow syndrome is a very rare genetic disorder that affects the development of the skeleton and other body parts from before birth. Experts have reported fewer than 200 cases of the recessive form and only around 50 families with the dominant form. The two forms differ in the gene involved, how they are inherited, the symptoms, and the severity. [1]

It is also known as fetal face syndrome, Robinow dwarfism, mesomelic dwarfism-small genitalia syndrome, and Robinow-Silverman or Robinow-Silverman-Smith syndrome. [1]

What are the symptoms and warning signs of Robinow syndrome?

Symptoms vary widely depending on the type and how severe it is. The autosomal recessive form is generally more severe than the autosomal dominant form. [1]

Common Signs

Details

Facial features

"Fetal facies" appearance.

Broad or bulging forehead, prominent and widely spaced eyes, short upturned nose, triangle-shaped mouth, small chin or jaw, wide or sunken nose bridge, large head, and unusually positioned ears.

Skeleton

Short bones and spine or rib differences.

Short arms and legs, short fingers and toes (brachydactyly), curved spine (scoliosis), and fused or missing ribs.

Growth

Delayed growth and short stature.

Present in most people.

Dental

Crowded teeth, overgrown gums, or cleft palate.

Often needs care from a dentist, orthodontist, or oral surgeon.

Development and organs

Developmental delays and, in some people, kidney or heart problems.

Most people do not have intellectual disabilities later in life.

Genitals

Underdeveloped genitalia.

In some people the genitals are not obviously male or female.

Short stature can have many causes (see our guide to dwarfism), and curvature of the spine is covered in our scoliosis guide.

What causes Robinow syndrome, and how is it inherited?

Robinow syndrome is caused by a genetic mutation. The gene involved depends on the type, and it affects how the condition is inherited. [1]

  • Autosomal recessive Robinow syndrome: Caused by mutations in the ROR2 gene, which is thought to make a protein involved in forming the skeleton, heart, and genitals. A child must inherit two copies of the abnormal gene, one from each parent. The parents are carriers and have no symptoms. If two carriers have a child together, the child has a 25% chance of having this form. [1]

  • Autosomal dominant Robinow syndrome: May involve several genes, including FZD2, WNT5A, DVL1, and DVL3, which make proteins involved in early development. It occurs when a person inherits an abnormal gene from one parent or when a mutation happens randomly. [1]

  • Spontaneous mutations: Rarely, the condition results from a new mutation during fetal development that was not passed down. Sometimes no genetic mutation can be found. [1]

  • Osteosclerotic variant: A minority of people with the dominant form (due to a DVL1 mutation) have bones that are harder than normal. [1]

Inheritance patterns of Robinow syndrome: autosomal recessive with two carrier parents (25% affected, 50% carriers, 25% unaffected) and autosomal dominant with one affected parent (50% chance for each child), plus new mutations. – rinnit.com
The recessive form needs a gene change from both parents, while the dominant form needs one changed gene or a new mutation.

How is Robinow syndrome diagnosed?

Robinow syndrome is usually diagnosed from physical signs, often at birth or in early childhood. Genetic testing confirms the diagnosis. [1]

  1. Physical examination: Looking at facial features, limb length, spine and rib alignment, and teeth. [1]

  2. Molecular genetic testing: A laboratory test on a sample of blood, saliva, cheek swab cells, or skin to look for a gene mutation. [1]

  3. Prenatal testing: If the condition runs in the family, a provider may recommend testing the developing baby with chorionic villus sampling (placenta sample) or genetic amniocentesis (amniotic fluid sample). [1]

  4. Imaging and organ checks: Providers may use imaging to look at skeletal differences and check whether the heart and kidneys are involved.

How is Robinow syndrome managed and treated?

Treatment depends on the individual's symptoms. Care often involves a team of specialists. [1]

Your Care Team May Include

  • Cardiologist (heart)

  • Dentist, orthodontist, or oral surgeon (teeth and jaw)

  • Endocrinologist (hormones related to growth and genital development)

  • Pediatrician

  • Physical therapist (to improve movement)

  • Orthopedic surgeon (bones and joints)

Common Interventions

  • Braces or casts: To support affected bones. [1]

  • Dental devices: Braces and other oral devices to correct dental problems. [1]

  • Hormone therapy: To improve growth or genital development. [1]

  • Exercise and physical therapy: Special exercises to strengthen the body and improve function. [1]

  • Surgery: To correct skeletal or genital abnormalities. [1]

  • Genetic counseling: For people with Robinow syndrome and their families. [1]

Four-step cycle for managing Robinow syndrome: genetic testing for diagnosis, a multidisciplinary team including a cardiologist, orthopedist, and dentist, interventions such as surgery, braces, and hormone therapy, and long-term support with physical therapy and genetic counseling. – rinnit.com
Care combines genetic diagnosis, a multidisciplinary team, targeted treatments, and long-term support.

What is the outlook for Robinow syndrome, and can it be prevented?

The outlook varies with the symptoms and how severe they are. Rare heart and kidney problems can shorten lifespan, and most people do not have intellectual disabilities later in life. Unless couples use preimplantation genetic testing, there is no way to prevent the mutation that causes Robinow syndrome. If you or someone in your family has the condition, a genetic counselor can help you understand the chances of passing it on. [1]

Conclusion

Robinow syndrome is a lifelong genetic condition, and its skeletal, facial, and genital differences can be significant. Specialists may be able to correct some skeletal and genital abnormalities and help children function better. Early diagnosis, coordinated care from a team of specialists, and genetic counseling help families plan ahead.

What are the next steps if you have Robinow syndrome?

If your child has developmental delays or unusual skeletal or facial features, talk to your pediatrician about a referral to a geneticist. If Robinow syndrome runs in your family, ask about genetic counseling and prenatal testing so you understand the risks and can prepare for the care your child may need.

Frequently Asked Questions

No. Some children have developmental delays, but most people with Robinow syndrome do not have intellectual disabilities later in life. [1]

The face of a person with Robinow syndrome can look similar to the face of a developing fetus, for example with a broad forehead and widely spaced eyes. [1]

If the condition runs in the family, a provider may recommend genetic testing of the developing baby, using a placenta sample (chorionic villus sampling) or amniotic fluid (genetic amniocentesis). [1]

The lifespan of someone with Robinow syndrome varies with the symptoms and their severity. Rare heart and kidney problems can shorten lifespan. [1]

Extremely rare. Experts have reported fewer than 200 cases of the recessive form and only around 50 families with the dominant form. [1]

Yes. People often have short stature and short bones in the arms and legs. The condition is sometimes called mesomelic dwarfism because the middle segments of the limbs are especially short. [1]

Treatment is aimed at symptoms rather than the underlying gene change. Specialists may be able to correct skeletal and genital abnormalities and help a child function better. [1]

Heart and kidney problems can occur, so providers often ask whether these organs are involved and may recommend monitoring. [1]

ROR2 causes the recessive form. Several genes, including FZD2, WNT5A, DVL1, and DVL3, may be involved in the dominant form. [1]

Autosomal recessive and autosomal dominant. They differ in the gene involved, how they are inherited, the symptoms, and the severity. The recessive form is usually more severe. [1]

Crowded teeth, overgrown gums, and sometimes cleft palate. Braces, oral devices, and care from a dentist, orthodontist, or oral surgeon can help. [1]

Surgery can correct some skeletal and genital abnormalities and improve function. Braces or casts may also be used to support affected bones. [1]

Hormone therapy may be used to improve growth or genital development, usually under the care of an endocrinologist. [1]

Pain is not a defining feature, but skeletal problems such as scoliosis can cause discomfort. Tell your care team about any pain.

Parents and siblings may want genetic testing and counseling to understand their chances of being carriers or passing the condition on. Carriers of the recessive form have no symptoms. [1]
