Every person has a unique blend of genes, but if some are missing in certain areas, the result can be dramatic, devastating and fascinating.
Williams Syndrome is a rare disorder that most people aren't aware of, something one group is working to change by raising awareness during Williams Syndrome Awareness Week.
On Sunday, there was nothing but enthusiasim when it came to the swing set in the yard for 3 year old Ellie Sockol.
When Ellie was 9 months old, her mother Jenny Sockol noticed her youngest little girl appeared to be falling behind.
"It's hard not to compare your children developmentally, but I noticed she wasn't up to the normal milestones," said Sockol. "She wasn't walking or talking."
At two years old, a blood test would confirm what Jenny Sockol's online research had already pointed to. Ellie was diagnosed with Williams Syndrome.
It's a rare genetic disorder that spontaneously occurs at conception, and can affect anyone.
"We looked at all the characteristics and we went to the William Syndrome dot org website," said Sockol. "Looking at all the 40 characteristics, it was this one."
One in 10,000 people have Williams Syndrome worldwide. It means that person is missing a group of genes on chromosome 7. Those with Williams Syndrome share unique physical appearances, can face heart problems, along with developmental disabilities. But many also have gifts including sensitive hearing, a talent for music and heightened social skills.
Even at just 3 years old, Ellie's openess is endearing. Her family has connected online with other families coping with Williams Syndrome in the Holland area, and around the world.
Right now, the goal is to raise awareness about Williams Syndrome, and live their lives appreciating everyday.
"I think it's important because so few people know about it," said Sockol. "We've got small communities scattered across the country. We are just trying to get the word out there and let everyone know what beautiful kids they are."
