Our little boy was happy and healthy until we found out his ‘normal’ birthmarks were a sign of a devastating disease described as a ‘ticking time bomb’

When Jennifer Pearsall took her youngest son Grayson to hospital after an allergic reaction to eggs, doctors were much more concerned about the 'birthmarks' on his back.

The one-year-old's spots appeared after he was born and, like most parents, assumed they were completely normal.

However, that was far from the case; those little brown spots were actually a sign of an incurable genetic condition that his mother described as a “ticking time bomb.”

Jennifer, 40, from Brisbane, remembers the moment she opened a letter in late January 2018 explaining Grayson had neurofibromatosis type 1 (NF1). They had undergone a lengthy testing process and an MRI a few weeks earlier.

The condition causes flat, dark spots on the skin and the growth of benign tumors just under the skin. These tumors can grow in the nerves near the spinal cord and brain, and can become cancerous at any time.

“We haven't had a phone call, just a letter,” she told FEMAIL.

“In that situation, you pretty much have to absorb the information in front of you. There is nothing you can do about it. You're grieving, you're angry, you're thinking, “Why us? Why Grayson?” but this will not define him.”

Neurofibromatosis Type 1 (NF1) is the most common type of condition; it affects an estimated one in 3,000 people in Australia.

The 'birthmarks' on Grayson's back are known as 'café au lait spots' – and are the main indicator of the disease.

Now he has hundreds of spots on his body and they keep appearing.

'When I first saw the pediatrician in the hospital, he said: “You need to take action on this now, he needs to see a genetic specialist, this is something you cannot ignore.” Then I started to panic,” Jennifer said.

As Grayson grew, he had a larger head circumference than normal, which was another indicator of NF.

Now he has occupational therapy, psychology, speech therapy and physiotherapy. He has also been diagnosed with ADHD and ASD; Research has shown that both are more common in children with NF1.

Grayson, now seven, has numerous tumors on his spine and brain, but fortunately they have not yet caused any side effects.

Although the tumors are benign, they can become cancerous at any time – something Jennifer described as a 'ticking time bomb'.

“His tumors are pressing against his spine and brain – only some can be removed, but we cannot stop them from growing back,” she said. 'The biggest struggle is the fact that he has it for the rest of his life – there is no cure – and it breaks my heart as a parent.

“A few weeks ago he asked my husband Tim a question in the car and said, 'Dad, why can't my tumors go away?'

The largest is on its 13 cm spine. There are also tumors in his brain behind his eyes and a 6.5 cm tumor next to his heart.

'It's just a monitoring game. Every MRI is a horrible experience: waiting for the results and not knowing what it could be,” Jennifer said.

'My assumption is that it is a ticking time bomb; you don't know when things are going to change or when things are going to get so serious that he's going to have to spend a lot of his days in a hospital.

'There is no prevention for these children or adults diagnosed with NF. It just sits there waiting to take its toll on their bodies. We will try to make it as normal as possible and advocate for some form of NF awareness out there.”

Grayson loves football but cannot play the sport because his parents worry that any rough movement could affect one of his tumors and cause further damage.

“We asked him if he wanted to be a referee because then he can still play the sport, no one can touch him and he can be the boss of everyone,” Jennifer said with a laugh.

'I don't think he'll ever be able to get a massage either. That's a strange thought, because you shouldn't touch tumors.'

Jennifer and Tim do not have NF, but the condition is passed on through genetics and can occur 'spontaneously'.

If Grayson were to have children later in life, he would have a 50 percent chance of passing this on to his children.

Jennifer said there is one “lifelong” drug that will keep the condition from worsening, but it would cost the family $2,500 a month.

Other common symptoms of NF1 include benign swelling of the nerves known as neurofibromas, freckles in unusual places such as the groin and armpits, and freckles in the iris (lic nodules).

Earlier this month, the family attended the Color Run to raise money and awareness about NF.

What is neurofibromatosis type 1 (NF1)?

Neurofibromatosis (NF) is a group of genetic disorders: NF1, NF2 and schwannomatosis (shwon-oh-ma-toe-sis).

NF1 (also known as von Recklinghausen disease) is the most common type, estimated to affect one in 3000 people in Australia.

NF1 is a variable condition, meaning children can be affected in many different ways. It usually causes freckles or spots, usually on the skin or eyes, and benign (non-cancerous) swellings or lumps around the nerves.

Many children with NF1 have no or very few medical problems, but about four in ten children will experience some complications. Treatment for NF1 depends on the specific medical problems your child develops.

NF1 is something you are born with and it is not contagious. Some symptoms of NF1 only appear later in life, often around puberty.

Symptoms include:

Café au lait places: These are flat coffee-colored spots on the skin. It is common to have one or two of these spots, but people with NF1 always have six or more of these moles, which are always present before the age of five. The number of café au lait spots is not related to the severity of the disease and does not cause any problems or symptoms.

Freckles: People with NF1 often have freckles in unusual places, such as the armpit or groin. They also usually appear later (between the ages of three and five). Skin freckles are smaller than café au lait spots.

Neurofibromas: These are benign swellings around the nerves, usually seen as small lumps in or under the skin. Neurofibromas are not normally seen in young children but tend to increase in number and size around puberty and into adulthood. They are usually small and generally do not cause any physical complaints.

Lisch nodules: These are small freckles in the iris (the colored part of the eye). Lisch nodules develop during puberty in people with NF1. They are usually only seen when examined with a special lamp and never affect vision or cause other symptoms.
