Labcorp Genetics (formerly Invitae), Labcorp RCV001908818 SCV002172421 uncertain significance MHC class II deficiency 2021-09-16 criteria provided, single submitter clinical testing This sequence change affects codon 99 of the CIITA mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CIITA protein. This variant is present in population databases (rs757438997, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with CIITA-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
