Cartilage hair hypoplasia does not affect thinking and learning abilities.
What Causes Cartilage Hair Hypoplasia?
Cartilage hair hypoplasia happens because of a gene mutation (change). Many different mutations can lead to the condition, and each causes different symptoms.
Cartilage hair hypoplasia is an inherited condition. Children who have it got one changed gene from each parent. Children who get one gene from one parent don’t have symptoms, but they can pass the changed gene to their children.
A genetic counselor can help families understand how the condition can run in families.
How Is Cartilage Hair Hypoplasia Diagnosed?
Most children with cartilage hair hypoplasia are diagnosed around their first birthday. To make a diagnosis, doctors do an exam and might order tests such as:
Children with cartilage hair hypoplasia can have symptoms that range from mild to severe. Regular medical care can help your child stay well and manage any problems. Be sure to:
Go to all doctor visits.
Give any medicines as prescribed.
Call your doctor as instructed.
Also:
Treat your child according to their age, not their size, and encourage others to do the same.
Talk about cartilage hair hypoplasia as a difference rather than a problem. Your attitude can help your child develop good self-esteem.
Find ways to adapt. For example, get a light switch extender and a stepstool so your child can turn the lights on and off. Encourage your child’s school to make similar changes to help your child, such as lower chairs and/or feet support.
Answer questions as simply as possible. If someone asks why your child is short, for example, say, “Jason is shorter because he has a problem with his bones.” Then, mention something special about your child. For example, “Nothing holds Jason back. He loves to sing.” This shows your child that many things make them special.
Teach your child that being teased or bullied is not OK. If your child is teased or bullied at school, work with your child, teachers, and administrators to end it.
Encourage your child to find a hobby or activity to enjoy. Help your child try different activities like music, art, computers, writing, and photography.
