Genes affected

ZMYND11 (HGNC:16966): (zinc finger MYND-type containing 11) The protein encoded by this gene was first identified by its ability to bind the adenovirus E1A protein. The protein localizes to the nucleus. It functions as a transcriptional repressor, and expression of E1A inhibits this repression. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 4 uncertain in NM_001370100.5
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-248370-G-A is Pathogenic according to our data. Variant chr10-248370-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 225254.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.3341695). . Strength limited to SUPPORTING due to the PP5.

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The S421N variant in the ZMYND11 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The S421N variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The S421N variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. The S421N variant is a strong candidate for a pathogenic variant; however, the possibility it may be a rare benign variant cannot be excluded.
