BIRTH TO 2 YEARS

Do you think your infant or toddler may have achondroplasia? Have they already been diagnosed? This resource can help you learn more and find support

Getting a diagnosis after birth

Many children with achondroplasia are not diagnosed until after birth

Physical features of achondroplasia usually don’t show up on ultrasounds until the third trimester of pregnancy, after routine ultrasounds have already taken place. Even after birth, achondroplasia may not be obvious at first because children may have a similar length in the newborn stage. However, it tends to become more obvious as children age. Many parents start to suspect that something is off when their child is not developing like other children their age.

Clinical evaluation, X-rays, and genetic testing are the typical ways to receive a diagnosis after the baby is born. If you suspect your child has achondroplasia, talk to their pediatrician about testing.

Some clinical and X-ray characteristics that may be seen after birth include:

  • Clinical characteristics:
    • Short stature
    • Larger than average size head
    • Gap between the third and fourth fingers in the hands
    • Long, near-average length trunk
  • X-ray features:
    • Shortened long bones in the arms and legs
    • Square shape of the pelvis

Genetic testing

Although achondroplasia can be diagnosed based on physical features alone, genetic testing can confirm the diagnosis. This testing can distinguish achondroplasia from other types of skeletal dysplasia, like hypochondroplasia.

Potential Medical Complications

Children with achondroplasia may have specific medical needs, though most will not experience everything listed here. Proactive care and support can make a meaningful difference. Learn more below about how to help support your child’s health.

Stay Prepared with this Medical Checklist

It’s important to make sure your child has the right examinations at the right times.

Oxygen therapy for sleep apnea

Oxygen therapy can help children with central or obstructive sleep apnea breathe better. If your child was recently put on oxygen therapy, you may feel overwhelmed by all the medical equipment that has made its way into your home, but you will become an expert.

Ask your child’s health care provider if they have any tips on getting familiar with the medical equipment used for oxygen therapy.

You can also review the guide we developed on using oxygen equipment. If someone else will be caring for your child, sharing the guide below may help.

Your child’s oxygen therapy does not need to prevent you from leaving the house and living life. For information about traveling with oxygen therapy, see the recommendations provided by the American Lung Association.

Preparing for surgery

Many children with achondroplasia undergo surgery without any problems, but they are at a greater risk of challenges related to anesthesia, such as:

  • Uncontrolled neck movement leading to squeezing of the spinal cord and breathing problems
  • Receiving the wrong medication dosage
  • Difficulties with inserting an intravenous (IV) line due to limited elbow extension
  • Difficulties with placing a breathing tube if it’s needed

It’s important to ensure that your child receives care from an anesthesiologist experienced in treating patients with achondroplasia. You can also talk to your child’s care team about the Skeletal Dysplasia Management Consortium’s guidelines, which outline best practices to support safe anesthesia care.
