| Ambry Genetics | RCV003172165 | SCV003858951 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2022-11-22 | criteria provided, single submitter | clinical testing | The c.401-5C>G intronic variant results from a C to G substitution 5 nucleotides upstream from coding exon 5 in the LZTR1 gene. This nucleotide position is well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration may weaken the native splice acceptor site and will result in the creation or strengthening of a novel splice acceptor site; however, direct evidence is insufficient at this time (Ambry internal data). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV003730426 | SCV004532164 | uncertain significance | not provided | 2024-01-21 | criteria provided, single submitter | clinical testing | This sequence change falls in intron 4 of the LZTR1 gene. It does not directly change the encoded amino acid sequence of the LZTR1 protein. This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with LZTR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2452071). 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. |
