Labcorp Genetics (formerly Invitae), Labcorp RCV003619328 SCV004475615 uncertain significance Neutrophil immunodeficiency syndrome 2023-11-03 criteria provided, single submitter clinical testing This sequence change affects codon 75 of the RAC2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the RAC2 protein. This variant also falls at the last nucleotide of exon 3, which is part of the consensus splice site for this exon. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with RAC2-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus 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.
