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=0.0085400045).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000473 (72/152174) while in subpopulation AFR AF= 0.00171 (71/41514). AF 95% confidence interval is 0.00139. There are 1 homozygotes in gnomad4. There are 36 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.2756C>T (p.T919I) alteration is located in exon 12 (coding exon 11) of the SLX4 gene. This alteration results from a C to T substitution at nucleotide position 2756, causing the threonine (T) at amino acid position 919 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
