Galloway-Mowat syndrome is a rare autosomal-recessive condition characterized by
nephrotic syndrome associated with microcephaly and neurological impairment.
Through a combination of autozygosity mapping and whole-exome sequencing, we
identified WDR73 as a gene in which mutations cause Galloway-Mowat syndrome in
two unrelated families. WDR73 encodes a WD40-repeat-containing protein of unknown
function. Here, we show that WDR73 was present in the brain and kidney and was
located diffusely in the cytoplasm during interphase but relocalized to spindle
poles and astral microtubules during mitosis. Fibroblasts from one affected child
and WDR73-depleted podocytes displayed abnormal nuclear morphology, low cell
viability, and alterations of the microtubule network. These data suggest that
WDR73 plays a crucial role in the maintenance of cell architecture and cell
survival. Altogether, WDR73 mutations cause Galloway-Mowat syndrome in a
particular subset of individuals presenting with late-onset nephrotic syndrome,
postnatal microcephaly, severe intellectual disability, and homogenous brain MRI
features. WDR73 is another example of a gene involved in a disease affecting both
the kidney glomerulus and the CNS.
