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
Oct 23, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1345 of the SLX4 protein (p.Arg1345Cys). This variant is present in population databases (rs200310925, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with SLX4-related conditions. ClinVar contains an entry for this variant (Variation ID: 526385). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

SLX4-related disorder Uncertain:1
Apr 17, 2023
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The SLX4 c.4033C>T variant is predicted to result in the amino acid substitution p.Arg1345Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.044% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-3639606-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
