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]

The c.5441G>A (p.R1814H) alteration is located in exon 15 (coding exon 14) of the SLX4 gene. This alteration results from a G to A substitution at nucleotide position 5441, causing the arginine (R) at amino acid position 1814 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1814 of the SLX4 protein (p.Arg1814His). This variant is present in population databases (rs201036767, gnomAD 0.009%). 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: 456337). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
