Byler disease is an inherited condition caused by a faulty gene. In children with Byler disease, cells in the liver cannot release bile, a fluid that helps the body digest food. As a result, bile builds up in the liver, leading to symptoms such as jaundice, itching, impaired growth, and delayed puberty. Byler disease is one of a group of diseases known as progressive familial intrahepatic cholestasis.
Children are typically around 3 months old when diagnosed with Byler disease.
If your child has been diagnosed with Byler disease, we want you to know that you are not alone – the Center for Rare Disease Therapy is here to help. Here’s what you can expect when you come to us for a consultation.
An appointment with one of our pediatric liver specialists will be scheduled within a reasonable time based on our child’s condition. We will require a copy of your child's medical records and will determine how soon your child should be seen based on their medical information. Reviewing your child's records ahead of the first appointment allows us to avoid repeating tests that your child has already had and to coordinate visits with other specialists as needed.
To make an appointment, please call Jodie Vento at 412-692-7273 or send an email to firstname.lastname@example.org.
You can expect your first visit to take about 3 to 4 hours.
Your child will receive a complete evaluation to establish or confirm a precise diagnosis and determine how much the disease has affected the child.
Because we work as a team at the Center for Rare Disease Therapy, your child may be seen by other specialists, if not on the first visit, then on follow-up visits, including a hearing specialist, a surgeon, a nutritionist, and a genetic counselor.
We understand that the whole family is affected when a child has a rare disease. We see each family as our partner in caring for their child. We think the best approach to caring for a child with a rare disease emerges when we combine our depth of experience in rare diseases with your expertise in what’s best for your child.
We will talk with you about what we think is likely to happen with your child in the near future and about options we can suggest for treating and caring for your child. If surgery is an option, we will help you understand what the surgery entails and what you may need to do to prepare for it. We will also talk with you about what you can do at home to care for your child and improve his or her quality of life. Please feel free to ask our specialists any questions you have about your child’s disease, treating and caring for your child, or anything else that is on your mind.
By the end of your visit, you will have a care plan tailored to your child’s needs and an appointment for a follow-up visit in 3 months. You will be introduced to our clinical nurse practitioner, who is available by phone or video conference to help you with any concerns you have between now and your next appointment.
Depending upon the types of tests that the doctors order, you can expect to receive a phone call within 2 weeks to explain test results and discuss recommended next steps. Test results are also available on Children's patient portal, myCHP, which is provided at no cost to patients, parents, and guardians.
