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]

SLX4 NM_032444.3 exon 12 p.Val894Gly (c.2681T>G): This variant has not been reported in the literature and is present in 0.1% (11/10370) of Ashkenazi Jewish alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/16-3640958-A-C). This variant is present in ClinVar (Variation ID:319164). This variant amino acid Glycine (Gly) is present in multiple mammals and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Variant summary: BTBD12 c.2681T>G (p.Val894Gly) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00033 in 282824 control chromosomes (gnomAD). c.2681T>G has been reported in the literature in individuals affected with breast cancer and/or ovarian cancer (examples: Bakker_2012, Song_2019). These report(s) do not provide unequivocal conclusions about association of the variant with Fanconi Anemia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 22911665, 36916425, 32546565). Seven submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces valine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 894 of the SLX4 protein (p.Val894Gly). This variant is present in population databases (rs145137472, gnomAD 0.1%). This missense change has been observed in individual(s) with breast cancer and/or ovarian cancer (PMID: 22911665, 32546565, 36916425). ClinVar contains an entry for this variant (Variation ID: 319164). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The glycine 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. -
