My son's diagnosis is Developmental Coordination Disorder. His DCD primarily affects his fine motor skills, though his balance is also disastrous and he has joint hypermobility. He looks very fidgety ADHD in a classroom, but has no issues with concentration, memory, organization or recall.
Depending on who you ask, DCD is a "light" form of dyspraxia, though I've heard different versions of this from different medical professionals. It was simple to get a 504 with DCD that allows him to type his schoolwork, have reduced in class work or extended time, take standardized tests individually so he can wiggle without getting in trouble- though we currently homeschool.
This website might help- it's not 2e related but a lot of it made sense for us.
