Labcorp Genetics (formerly Invitae), Labcorp RCV000651167 SCV000773017 uncertain significance Cryptosporidiosis-chronic cholangitis-liver disease syndrome 2017-11-02 criteria provided, single submitter clinical testing This sequence change affects codon 151 of the IL21R mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the IL21R protein. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with IL21R-related disease. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
