Green List (high evidence)

Difficult one - AD and AR variants associated with CMT phenotype are very well described. OPA+ syndrome which includes cerebellar atrophy is limited to a single patient in the literature (we may have an additional family within our own patient cohort). Think ok for Green given the strong link with neurological disease in general
