Abstract
Wilms tumour (nephroblastoma) is a renal embryonal tumour that is frequently caused by constitutional variants in a small range of cancer predisposition genes. TRIM28 has recently been identified as one such gene. Previously, observational data strongly suggested a parent of origin effect, whereby Wilms tumour only occurred following maternal inheritance of a pathogenic genetic variant. However, here we report a child with bilateral Wilms tumour who had inherited a pathogenic TRIM28 variant from their father. This finding suggests that genetic counselling for paternally inherited pathogenic variants in TRIM28 should include discussion of a potential risk of Wilms tumour.
