Reply To: Mother is a carrier worried about son
Hi And welcome to forum
Like you say only 100% way of knowing is the testing.
I cant think of any symptoms that would cause toe curling apart from possibly toe walking where the walker cant put heal down on ground.
Try at this stage not to look too much into depth. Google can be a great tool or a dangerous one.
I have read articles that carriers can sometimes show some traits of MD without having the full physical condition.
