RCV000473406 | SCV000547946 | uncertain significance | Familial melanoma | 2023-08-07 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 408334). This variant has not been reported in the literature in individuals affected with CDK4-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change falls in intron 7 of the CDK4 gene. It does not directly change the encoded amino acid sequence of the CDK4 protein. It affects a nucleotide within the consensus splice site. |
| Ambry Genetics | RCV001027260 | SCV001189791 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-08-01 | criteria provided, single submitter | clinical testing | The c.819+4C>T intronic variant results from a C to T substitution 4 nucleotides after coding exon 6 in the CDK4 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
