GeneDx RCV000220735 SCV000279356 uncertain significance not provided 2015-06-02 criteria provided, single submitter clinical testing To our knowledge, the c.227-18 T>C variant has not been published as a mutation, nor has it been reported as a benign polymorphism. It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. In-silico splicing models are not informative or consistent regarding the effect of this variant on splicing, with one model predicting that it may destroy the natural splice donor site of intron 2. The nucleotide which is altered, a thymine (T) at the -18 position of intron 2, is conserved across species. Regardless, in the absence of RNA or functional studies, the actual effect of this sequence change in this individual would be unknown. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant.
