The majority of affected individuals have some evidence of hypothalamic-pituitary axis dysfunction when detailed measurement of growth hormone and gonadotropins is undertaken [Tziaferi et al 2008]. 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. Thalidomide treats cancer and some skin conditions. Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. Here we provide a detailed description of the clinical features associated with SOX2 mutations in the five individuals with reported mutations and four newly identified cases (including the first reported SOX2 missense mutation). OMIM; This may be an inappropriate acronym, as it implies that coloboma is an intrinsic part of all microphthalmia, which is not the case: coloboma has been reported but is not a common feature.
