Growing up, Dylan Rosnick just wanted to play baseball, a simple enough request for a child growing up in the Loudoun County exurbs.

He wanted to tie his shoes, too, and hold a pencil the right way and button his shirt and brush his teeth. There’s not a lot of guidance, though, for a child with Proteus syndrome, a genetic disorder that affects fewer than one in 1 million births worldwide, according to the National Institutes of Health.

It causes overgrowth in bones, skin and other tissues. Those organs grow out of proportion with other tissues in the body.

For Rosnick, the most obvious features impacted by the condition are his fingers. Three on each hand are overgrown, maybe six inches long and the width of an extra-wide thumb.

And Dylan Rosnick, large fingers and all, wanted to play baseball. . . .
