Theres a genetic condition which can start with simple birthmarks that one Sioux Falls, South Dakota, family knows well.

Its called neurofibromatosis type one or NF1 and it is a disorder that can cause tumor growth, vision problems and skin changes.

Rachel Li, M.D., specializes in clinical and pediatric genetics at Sanford Childrens.

It can begin with the development of caf au lait spots, which are brown birth marks across the skin.

Dr. Li said tumors can grow underneath the skin and along nerves, including the optic nerve in the brain.

A majority of the time, the tumors are not cancerous, Dr. Li told Sanford Health News. But when were talking about brain tumors, theres only so much space in there so we monitor those very closely. And then we can start treatment with medications if we start noticing changes associated with that.

She said while all genetic disorders are rare, NF1 affects 1 in around 3,000 to 4,000 patients.

Fifty percent of the time its a new finding in a family or patient without family history, and the other 50% its inherited from a parent or relative, she added.

Candice Hazel and Roland Marshalls youngest, Logan, had some unique birthmarks which led to a diagnosis in 2022.

But that diagnosis was just the beginning.

When I met Roland, he had four girls, Hazel explained. One of the girls had a lot of caf au lait spots and he said she was diagnosed with neurofibromatosis.

Coincidentally, Hazel was already receiving care for McCune-Albright syndrome which is associated with caf au lait birthmarks.

So when she and Roland noticed her son Logans birthmarks, she contacted her provider at Sanford Health, and the entire family of seven underwent genetic testing.

The results showed Logan, his dad Roland, and two half-sisters were all living with NF1.

Those with NF1 can have variable features or different symptoms, even with the same genetic change.

Its been a whirlwind with a lot of emotion and worry, especially with the risk for tumors and optic issues. As a parent, its scary, Hazel said. Were very lucky to have someone close to home who specializes in NF1 and who makes you feel comfortable.

In most cases, a pediatrician or other primary care provider can notice the first signs of the condition in a patients birthmarks.

Dr. Li said the clinical criteria includes two or more features but patients are evaluated with just one, including certain freckling on the arms or in the groin.

From there, the primary care provider can refer the patient and family to the genetics team and begin testing.

But its not always caught right away when a patient is young.

Its not uncommon for us to find a patient with NF1 but then Mom or Dad also has it, and we determine during a visit that the adult gets certain screenings and plugged in for care as well, Dr. Li said.

If a patient undergoes testing or meets clinical criteria for a diagnosis, they can be enrolled into the NF1 clinic.

Since 2022, the neurocutaneous clinic has been available for Sanford Health patients as the only multidisciplinary clinic in the Midwest for this rare genetic diagnosis.

We noticed there was a gap in care for our patients, Dr. Li said. They were all going to Mayo or Colorado, hours and hours away. We had all the services here available. So, we got together and said, I think we can start this clinic.

Theres definitely a large population of people who are really benefiting from getting all the care.

The Marshall family was among the first to participate in the clinic.

Logan was seen every six months early on and now everyone is seen once per year, Hazel explained. Its really helpful and convenient for us to have one place for our kids to get their care.

The clinic for patients with NF1, NF2 and tuberous sclerosis is a one-stop-shop for patients to see multiple providers with specialties in genetics, neurology, hematology and oncology, pediatric development, ophthalmology, as well as speech, physical and occupational therapies.

Theyre such a great family as far as just really following through with what needs to be done, making sure theyre getting their girls plugged in as much as possible, getting help with some of the school things that theyve come up with and seeing Logan grow up living his best life now, Dr. Li said.

The physicians and providers are so collaborative, and I think thats a really unique thing to find. Everyone is here to focus on what is best for patient care and for children. If that means creating an entirely new clinic for families, thats something theyre going to go forward and do. Its been a huge, huge benefit.
