RCV000521037 | SCV000618301 | likely pathogenic | not provided | 2017-02-27 | criteria provided, single submitter | clinical testing | The c.1088-1G>C variant in the TTC21B gene has been reported previously in two siblings with ciliopathy, however no second TTC21B variant was identified and the siblings were compound heterozygous for two variants in the CRB2 gene (Jaron et al., 2016). This splice site variant destroys the canonical splice acceptor site in intron 9. It is predicted to cause abnormal gene splicing, either leading to an abnormal message that is subject to nonsense-mediated mRNA decay, or to an abnormal protein product if the message is used for protein translation. The c.1088-1G>C variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). We interpret c.1088-1G>C as a likely pathogenic variant. |
