Dwarfism Care in Grand Rapids, MI

Dwarfism, sometimes called short stature, refers to a group of conditions where a person’s bones do not grow to the typical length. This can affect the arms and legs, the trunk, or both. There are more than 100 different medical conditions that can cause abnormal skeletal growth and result in dwarfism.

In Grand Rapids, Michigan, families affected by dwarfism can access specialized care through major health systems such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health. Local public health support is also available through the Kent County Health Department and Grand Rapids Public Health.

Achondroplasia: The Most Common Cause of Dwarfism

What is achondroplasia?

Achondroplasia is the most common type of short‑limb dwarfism and the most recognized skeletal dysplasia (abnormal bone growth). It occurs in about 1 in 25,000 births and affects boys and girls equally. Most cases are diagnosed at or shortly after birth based on physical features and x‑rays.

Although this page focuses on achondroplasia, much of the information also applies to other forms of skeletal dysplasia that cause dwarfism.

Typical growth and development

  • Most children with achondroplasia are born to average‑height parents.
  • Motor milestones (such as holding up the head, sitting, or walking) may be slightly delayed, largely because of differences in muscle tone and body proportions.
  • Intellectual development is typically normal.
  • Average adult height for people with achondroplasia is about:
    • 130 cm (around 4'3") for men
    • 125 cm (around 4'1") for women

People with dwarfism in Grand Rapids lead full, independent lives—attending local schools, colleges like Grand Valley State University and Grand Rapids Community College, and working in every type of career. Stature alone does not limit education, employment, or personal achievement.

Common Features of Achondroplasia

People with achondroplasia often have:

  • A trunk of relatively normal length
  • Disproportionately short arms and legs (especially upper arms and thighs)
  • Bowed legs (which may develop after the child starts walking)
  • Reduced joint mobility at the elbows
  • Other joints that seem overly flexible (“double‑jointed”) due to looser ligaments
  • Shortened hands and feet
  • A relatively large head with:
    • A prominent forehead
    • A flattened bridge of the nose
    • A mid‑face that appears flatter
  • Crowded teeth because the upper jaw is smaller

These features can vary in degree from person to person.

Skeletal Dysplasias and Other Causes of Dwarfism

“Dysplasia” means abnormal growth. Skeletal dysplasias are conditions where bones and cartilage grow differently from typical patterns. There are around 100 different skeletal dysplasias, including:

  • Achondroplasia – the most common form of disproportionate short‑limb dwarfism
  • Short‑trunk dysplasias – where the torso is shorter than average
  • Proportionate short stature – where the whole body is smaller but remains in proportion

In Grand Rapids, evaluation of skeletal dysplasias is often coordinated through pediatric and adult specialists at:

  • Corewell Health Helen DeVos Children’s Hospital
  • Trinity Health Grand Rapids pediatric and adult specialty clinics
  • Metro Health – University of Michigan Health orthopedic and genetics services

How Dwarfism and Achondroplasia Are Diagnosed

Diagnosis usually involves:

  • Physical examination – assessing body proportions and characteristic features
  • X‑rays – to look at bone shape and growth plates
  • Genetic testing – blood tests can confirm mutations known to cause achondroplasia and other skeletal dysplasias
  • Occasionally, tissue or bone samples in complex cases

Families in the Grand Rapids area are often referred to clinical genetics services at major hospital systems or to regional genetic centers in Michigan (such as those affiliated with the University of Michigan or Michigan Medicine).

Causes of Achondroplasia and Inheritance

Achondroplasia is caused by a change (mutation) in a specific gene involved in bone growth. This mutation affects how cartilage turns into bone, especially in the long bones of the arms and legs.

How often is it inherited?

  • About 80% of people with achondroplasia have average‑height parents.
    • In these cases, the genetic mutation happens spontaneously at conception, when the egg and sperm meet.
  • About 20% inherit the condition from a parent who also has achondroplasia.

Inheritance patterns

  • If one parent has achondroplasia and the other does not:

    • Each child has a 50% chance of inheriting achondroplasia
    • A 50% chance of having average stature

  • If both parents have achondroplasia, each pregnancy has:

    • 25% (1 in 4) chance of inheriting two copies of the gene (“double dominant” or homozygous achondroplasia), which is usually fatal in infancy (most affected infants do not live beyond 12 months)
    • 50% (1 in 2) chance of inheriting one copy of the gene and having achondroplasia
    • 25% (1 in 4) chance of inheriting no copies of the gene and having average stature

It is not fully understood why the mutation occurs or precisely how it leads to the specific physical features of achondroplasia.

Dwarfism and Achondroplasia in Infancy and Childhood

Children with achondroplasia may face certain medical challenges. In Grand Rapids, these are typically managed by a team that may include pediatricians, neurologists, orthopedists, ENT specialists, and pulmonologists at local hospitals.

Common issues in infancy and childhood

  • Breathing difficulties
    • Snoring and sleep apnea (pauses in breathing during sleep) due to narrowed nasal passages and upper airway
  • Ear infections
    • Narrowed Eustachian tubes and nasal passages can lead to frequent middle ear infections, which can affect hearing if not treated
  • Bowed legs
    • Legs may be straight at birth but can become bowed after walking begins
  • Reduced muscle tone
    • Infants may have softer muscle tone and need careful support of the head, neck, and back
  • Hydrocephalus
    • Increased risk (about 1 in 100) of hydrocephalus, a buildup of cerebrospinal fluid in the brain that can cause head enlargement and pressure
  • Narrow foramen magnum
    • The opening at the base of the skull (foramen magnum), where the spinal cord begins, may be smaller than usual
    • This can sometimes press on the brainstem and upper spinal cord, causing:
      • Breathing problems (including apnea)
      • Weakness, changes in reflexes, or other neurological signs

Because West Michigan winters are long and cold, children with dwarfism may spend more time indoors, which can contribute to lower physical activity and higher risk of weight gain. Local pediatricians often emphasize indoor physical therapy, swimming at community centers, and year‑round activity to support healthy growth and mobility.

Common Problems in Adulthood

Adults with achondroplasia and other forms of dwarfism may experience:

  • Nerve compression
    • Narrowing in the lower spine (lumbar region) can compress nerves, causing:
      • Numbness or tingling in the legs
      • Pain or weakness
  • Increased lumbar lordosis
    • A more pronounced inward curve in the lower back
  • Obesity
    • Maintaining a healthy weight is often challenging due to body proportions and joint strain
    • In Michigan, where winters can limit outdoor activity, tailored exercise and nutrition plans are especially important
  • Crowded teeth and dental issues
    • Small upper jaw can lead to crowded teeth and bite problems (malocclusion)

Pregnancy in women with achondroplasia is considered higher risk, and care should be coordinated with:

  • Maternal–fetal medicine specialists at Grand Rapids hospitals
  • Obstetricians familiar with skeletal dysplasias

Because of pelvic shape and maternal health, cesarean section is usually the recommended mode of delivery.

Treatment and Management of Dwarfism in Grand Rapids

Is there a cure for achondroplasia?

There is no cure for achondroplasia. The condition is not caused by a lack of growth hormone, so human growth hormone therapy is not effective and is not recommended as standard treatment.

Care focuses on:

  • Preventing and managing medical complications
  • Supporting healthy development and mental health
  • Providing social and family support

Medical and surgical care

Treatment plans are individualized and may include:

  • Surgery
    • To relieve pressure on the nervous system at:
      • The base of the skull (foramen magnum decompression)
      • The lower back (spine surgery for stenosis or nerve compression)
    • To help open blocked airways, such as removing enlarged adenoids or tonsils
  • Ear, nose, and throat (ENT) care
    • For recurrent ear infections, hearing problems, and breathing issues
  • Orthopedic care
    • For bowed legs, spinal curvature, and joint problems
  • Dental and orthodontic work
    • To correct crowded teeth and bite problems and maintain oral health

In Grand Rapids, these services are available through multidisciplinary teams at:

  • Helen DeVos Children’s Hospital (Corewell Health)
  • Trinity Health Grand Rapids
  • Metro Health – University of Michigan Health
  • Private orthopedic, ENT, and dental practices across Kent County

Emerging treatments

There are ongoing clinical trials for medications such as vosoritide, which aim to improve bone growth in children with achondroplasia. These treatments are still being studied and are not yet standard care.

Families in West Michigan interested in clinical trials may be referred to regional research centers, often at larger academic hospitals in Michigan, for evaluation and possible enrollment.

Genetic Counseling and Support in Grand Rapids

If your child or another family member has been diagnosed with dwarfism—or if dwarfism runs in your family—genetic counseling can be very helpful.

What genetic counselors do

Genetic counselors are trained in both genetics and counseling. They can:

  • Explain what dwarfism is and what causes it
  • Discuss how the condition is inherited and the chances of passing it on
  • Help you understand what the diagnosis means for your child’s health, development, and future
  • Review genetic testing options for you and other family members
  • Offer emotional support and guidance in decision‑making
  • Provide information that is sensitive to your family’s culture, values, and beliefs

You may choose to see a genetic counselor if:

  • You are planning a pregnancy and want to understand risks
  • Dwarfism is known or suspected in your family
  • You are considering prenatal tests or testing for other family members
