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]

Fanconi anemia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 25, 2024This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 49 of the SLX4 protein (p.Glu49Lys). This variant is present in population databases (rs139757085, gnomAD 0.1%). This missense change has been observed in individual(s) with breast cancer (PMID: 23840564). ClinVar contains an entry for this variant (Variation ID: 526398). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
