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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

A heterozygous missense variant was identified, NM_032444.2(SLX4):c.5040G>T in exon 14 of 15 of the SLX4 gene. This substitution is predicted to create a major amino acid change from arginine to serine at position 1680 of the protein, NP_115820.2(SLX4):p.(Arg1680Ser). The arginine at this position has low conservation (100 vertebrates, UCSC), and is not situated in a known functional domain. In silico software predicts this variant to be benign (Polyphen, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD population database at a frequency of 0.01% (28 heterozygotes, 0 homozygotes). An alternative nucleotide change resulting in the same protein alteration to serine has been reported in the gnomAD database at a frequency of 0.004% (12 heterozygotes, 0 homozygotes). In addition, an alternative residue change at the same location has been reported in the gnomAD database at a frequency of 0.0008%. The alternative nucleotide change resulting in a serine has been previously reported as a VUS (ClinVar), and this variant has been reported in the germline of a patient with head and neck squamous cell carcinoma (Chandrasekharappa, S. et al. (2017)). Based on information available at the time of curation, this variant has been classified as a VARIANT of UNCERTAIN SIGNIFICANCE (VUS) with LOW CLINICAL RELEVANCE. -
