Variant summary: The c.517-11T>C variant affects a non-conserved intronic nucleotide. Mutation taster predicts benign outcome for this variant. 4/5 programs in Alamut predict no significant effect on RNA splicing sites. However, these predictions are not confirmed by experimental studies. This variant is found in 4/119782 control chromosomes in ExAC at a frequency of 0.0000334, which does not exceed maximal expected frequency of a pathogenic allele (0.0007503). This variant has been reported in one BC/OC patient without strong evidence for causality. Because of the absence of clinical information and the lack of functional studies, the variant was classified as a variant of uncertain significance (VUS) until additional information becomes available.
