For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg224 amino acid residue in DEAF1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 24726472, 32959227, 33705764). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects DEAF1 function (PMID: 24726472). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DEAF1 protein function. ClinVar contains an entry for this variant (Variation ID: 133293). This missense change has been observed in individual(s) with autosomal dominant DEAF1-related conditions (PMID: 33705764). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 224 of the DEAF1 protein (p.Arg224Trp). (less)

In a 10-year-old boy with Vulto-van Silfhout-de Vries syndrome (VSVS; 615828), Vulto-van Silfhout et al. (2014) identified a de novo heterozygous c.670C-T transition (c.670C-T, NM_021008.2) … (more)
In a 10-year-old boy with Vulto-van Silfhout-de Vries syndrome (VSVS; 615828), Vulto-van Silfhout et al. (2014) identified a de novo heterozygous c.670C-T transition (c.670C-T, NM_021008.2) in the DEAF1 gene, resulting in an arg224-to-trp (R224W) substitution at a highly conserved residue in the SAND domain, which is essential for DNA binding. The mutation was not present in the dbSNP (build 139) or Exome Variant Server databases, or in over 2,000 in-house control exomes. In vitro functional expression studies demonstrated that the R224W mutation resulted in loss of the ability to repress the DEAF1 promoter, loss of DNA binding, loss of transcriptional activation of a reporter construct, and decreased interaction with XRCC6 (152690). The patient also carried a heterozygous c.1570C-T transition in the SCN2A gene (182390), resulting in an arg524-to-ter (R524X) substitution, which may have influenced the severity of the intellectual disability; however, the patient did not have a history of epilepsy.

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
