Ambry Genetics | RCV002318789 | SCV000850172 | likely pathogenic | Inborn genetic diseases | 2018-11-07 | criteria provided, single submitter | clinical testing | The c.976+5_976+10delGTGGGA intronic variant, located in intron 9 of the WDR45 gene, results from a deletion of 6 nucleotides within intron 9 of the WDR45 gene. This variant has been determined to be the result of a de novo mutation or germline mosaicism in one family with an isolated case of developmental delay, intellectual disability and seizures (Ambry internal data). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD) (Lek M et al. Nature, 2016 08;536:285-91). Using two different splice site prediction tools, this alteration is predicted by BDGP to abolish the native splice donor site, but is predicted to weaken (but not abolish) the efficiency of the native splice donor site by ESEfinder. In addition, RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). Based on the majority of available evidence to date, this variant is likely to be pathogenic. |
