Wilms Tumour
Gene: CTR9
Evidence for gene-disease association for Wilms tumour. Truncating variants are a rare cause of familial Wilms tumour.
PMID: 25099282
Inactivating CTR9 mutations found in 3 of 35 Wilms tumour families, through exome and Sanger sequencing. All variants were absent in 1,000 population controls and segregated with Wilms tumour in the family with second mutational event present in available tumours. CTR9 is a key component of the polymerase-associated factor 1 complex which has multiple roles in RNA polymerase II regulation and is implicated in embryonic organogenesis and maintenance of embryonic stem cell pluripotency.

2 female siblings with Wilms tumour (1 with bilateral Wilms tumour) and a pathogenic splice site variant in the CTR9 gene, leading to deletion of exon 9, and inherited from her asymptomatic father. The loss of heterozygosity in the tumour was confirmed.

3 affected siblings from 1 family with Wilms tumour (one presenting an aggressive bilateral tumour). They identified a novel CTR9 germline variant, located in a consensus splice acceptor site, which was found to segregate with Wilms tumour in this family. The variant leads to the skipping of the entire exon 9 in the mRNA, which is predicted to encode a truncated CTR9 protein, strongly suggesting that it is pathogenic. They also detected loss of heterozygosity in the index case tumour, which is consistent with CTR9 being a tumour suppressor gene.
