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]

Submissions by phenotype

Fanconi anemia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 27, 2022This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1434 of the SLX4 protein (p.Ser1434Leu). This variant is present in population databases (rs776332160, gnomAD 0.006%). This missense change has been observed in individual(s) with bone marrow failure (PMID: 30995915). ClinVar contains an entry for this variant (Variation ID: 407923). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
