The splice donor c.372+3_372+6del variant in USP53 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The c.372+3_372+6del variant is novel (not in any individuals) in 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain significance. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -

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 may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with USP53-related conditions. This variant is present in population databases (rs773537048, gnomAD 0.03%). This sequence change falls in intron 6 of the USP53 gene. It does not directly change the encoded amino acid sequence of the USP53 protein. It affects a nucleotide within the consensus splice site. -
