In addition to a pediatrician or internist, someone with either of these conditions will probably need an ophthalmologist, an ocularist and an oculoplastic surgeon. Almost all SOX2 pathogenic variants reported to date appear to represent heterozygous loss of function; thus, it is difficult to draw genotype-phenotype correlations. Dystonia and spasticity.
