A detailed phenotypic comparison of all reported WDR73-linked Galloway-Mowat syndrome patients with WDR73 negative patients showed that WDR73 mutations are limited to those with classical Galloway-Mowat syndrome features, in addition to cerebellar atrophy, thin corpus callosum, brain stem hypoplasia, occasional coarse face, late-onset and mostly slow progressive nephrotic syndrome, and frequent epilepsy.
We identified 10 patients from three CA and from two GMS families with WDR73 mutations including the original family described with CA, mental retardation, optic atrophy, and skin abnormalities (CAMOS).
