After 40 Years of Questions, These Siblings Finally Got an Answer

Theresa’s children, both in their 40s, were recently diagnosed with alpha-mannosidosis after almost a lifetime of experiencing symptoms.

On average, it takes seven years for a rare disease patient to receive an accurate diagnosis. For Theresa’s children, Jeremy and Alicia, it took nearly four decades.

Throughout their childhood and young adult lives, both Jeremy and Alicia experienced a range of strange, but seemingly unrelated symptoms. Theresa initially learned that her oldest, Alicia, might have an issue after visiting her pediatrician to have a hearing screening test in order to enter kindergarten. The pediatrician identified Alicia as having hearing loss and referred her to an audiologist.

“That threw us,” Theresa says. “We had no idea. She had good language and good social skills.”

When Theresa’s son, Jeremy, took the hearing test a few years later, he failed, too.

Both children developed cognitive challenges as a result of their hearing deficit, and Theresa explains it was difficult getting them through elementary school. “They both struggled in school. All the way through school. They were in special education their whole lives.”

When Alicia was 12 years old, she started developing cysts on her ankles. Doctors would remove the cysts but could never tell the family why the cysts kept developing. It was around this same age that Jeremy started complaining about leg pain when walking home from school and was diagnosed with severe scoliosis.

“He always was a kid that didn’t walk properly. But I could never put my finger on it. He had a strange gait and a really difficult time running,” Theresa explains.

When the siblings reached their 20s, their physical problems became even more pronounced. Jeremy’s walking difficulties intensified and Alicia developed a huge cyst, right before her wedding. The cyst, later identified as a mass rather than a simple cyst, was surgically removed.

A specialist told Alicia that she had bone loss and joint collapse, but offered no treatment and suggested she return for another examination in about a year. When Alicia returned a year later, her ankle was almost totally disintegrated. Today, Alicia’s right ankle is permanently fused.

When Jeremy was in his early 30s, Theresa explains, “everyone had noticed how his speech was getting more difficult to understand, how his walking was getting worse.”

Alicia’s speech took a nosedive, too. Her family thought she may have had a stroke. “We noticed she started to sound funny. Over the matter of a week, she was sounding more and more like she was drunk every time she spoke. She was choking on liquids and food,” Theresa recalls.

Alicia and Jeremy had repeatedly sought out medical explanations for their physical issues. Over the years, Jeremy received a handful of diagnoses including Scheuermann’s disease, cerebral palsy and spinocerebellar ataxia. It wasn’t until the entire family underwent genome sequencing, almost 40 years after Alicia failed her kindergarten hearing test, that the cause of Alicia and Jeremy’s symptoms was discovered. Theresa’s children were diagnosed with alpha-mannosidosis, a rare lysosomal-storage disorder, and she and her husband were identified as carriers.

Considering that their symptoms were so different, Theresa was surprised to learn her children had the same condition: “When we got the report, we were flabbergasted.”

“All of their symptomatology was looked at in isolation,” she explains.

“We were thrilled that we finally, finally had a diagnosis that explained what was going on with our kids. To me, that is a journey. Sometimes it wasn’t just a journey, it was horrific. There were lots of struggles. But we’re relieved that we can say ‘this is what they have’,” Theresa says.

Theresa said that some people thought she was foolish for doing genetic testing when she did since her children were already in their 40s. Still, she has no regrets and is grateful to have received a diagnosis.

“Just knowing means so much.”

The family has joined AllStripes to contribute their de-identified medical records to research for alpha-mannosidosis, to help develop treatments and grow knowledge about the condition. Hopefully, in the future, other patients and families won’t have to go through decades without an answer, or a treatment.

The de-identified data from Jeremy and Alicia’s medical records will be analyzed, along with data from other members of their condition community, with the intention to identify patterns and connections. Identifying these patterns and connections is key in advancing research and speeding up the development of treatments.

Like most things in their lives, Jeremy and Alicia’s reactions to their diagnoses were very different. Theresa explains that Jeremy insisted he was okay, but was worried about his sister. While Alicia wanted to learn more about alpha-mannosidosis, Jeremy did not ask any questions. But they were both happy to be able to contribute to research efforts for alpha-mannosidosis.
