Genes affected

SLX4 (HGNC:23845): (SLX4 structure-specific endonuclease subunit) This gene encodes a protein that functions as an assembly component of multiple structure-specific endonucleases. These endonuclease complexes are required for repair of specific types of DNA lesions and critical for cellular responses to replication fork failure. Mutations in this gene were found in patients with Fanconi anemia. [provided by RefSeq, Sep 2016]

Likely pathogenic, criteria provided, single submitter	clinical testing	Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago	Nov 03, 2021	SLX4 NM_032444.2 exon 10 p.Arg713* (c.2137C>T): This variant has not been reported in the literature is association with SLX4-related disease, but is present in 0.001% (1/68026) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/16-3594476-G-A?dataset=gnomad_r3). Please note, disease causing variants may be present in control databases at low frequencies, reflective of the general population, carrier status, and/or variable expressivity. This variant is present in ClinVar (Variation ID:526348). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant creates a premature stop at this codon which results in an absent or abnormal protein. Loss of function variants have been reported in association with disease for this gene (Stoepker 2011 PMID:21240277). In summary, data on this variant is highly suspicious for disease, but requires further evidence for pathogenicity. Therefore, this variant is classified as likely pathogenic. -

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 526348). This variant has not been reported in the literature in individuals affected with SLX4-related conditions. This variant is present in population databases (rs760126773, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Arg713*) in the SLX4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLX4 are known to be pathogenic (PMID: 21240277). -
