Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 18, 2023 | 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: 1008194). This variant has not been reported in the literature in individuals affected with RECQL4-related conditions. 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 sequence change falls in intron 4 of the RECQL4 gene. It does not directly change the encoded amino acid sequence of the RECQL4 protein. It affects a nucleotide within the consensus splice site. - |
