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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.044955164).
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000046 (7/152324) while in subpopulation EAS AF= 0.00116 (6/5192). AF 95% confidence interval is 0.000502. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Fanconi anemia Uncertain:1
Dec 21, 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 1589 of the SLX4 protein (p.Arg1589Cys). This variant is present in population databases (rs181782315, gnomAD 0.2%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with aplastic anemia (PMID: 36622392). ClinVar contains an entry for this variant (Variation ID: 456329). 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 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. -
