Description

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. 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 is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 636556). This variant has not been reported in the literature in individuals affected with NFKB1-related conditions. This variant is present in population databases (rs767638485, gnomAD 0.003%). This sequence change falls in intron 6 of the NFKB1 gene. It does not directly change the encoded amino acid sequence of the NFKB1 protein. It affects a nucleotide within the consensus splice site.
