Genes affected

DEAF1 (HGNC:14677): (DEAF1 transcription factor) This gene encodes a zinc finger domain-containing protein that functions as a regulator of transcription. The encoded proteins binds to its own promoter as well as to that of several target genes. Activity of this protein is important in the regulation of embryonic development. Mutations in this gene have been found in individuals with autosomal dominant cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Verdict is Pathogenic. Variant got 16 ACMG points.

• PM1: In a domain SAND (size 80) in uniprot entity DEAF1_HUMAN there are 8 pathogenic changes around while only 2 benign (80%) in NM_021008.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.984
• PP5: Variant 11-687941-C-T is Pathogenic according to our data. Variant chr11-687941-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 375554.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Published functional studies demonstrate that this missense variant, which is located in the SAND domain, causes impaired transcriptional regulation (Chen et al., 2017; Nabais Sa et al., 2019); Not observed in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 22941188, 28940898, 30923367, 30109124, 33994118) -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 212 of the DEAF1 protein (p.Gly212Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with DEAF1-related conditions (PMID: 28940898, 30923367). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 375554). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt DEAF1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects DEAF1 function (PMID: 28940898, 30923367). For these reasons, this variant has been classified as Pathogenic. -

Significance: not provided

Review Status: no classification provided

Collection Method: phenotyping only

Variant interpreted as Pathogenic and reported on 03-05-2018 by Lab or GTR ID 26957. Assertions are reported exactly as they appear on the patient provided laboratory report. GenomeConnect does not attempt to reinterpret the variant. The IDDRC-CTSA National Brain Gene Registry (BGR ) is a study funded by the U.S. National Center for Advancing Translational Sciences (NCATS) and includes 13 Intellectual and Developmental Disability Research Center (IDDRC) institutions. The study is led by Principal Investigator John Constantino MD PhD from Washington University. The BGR is a data commons of gene variants paired with subject clinical information. This database helps scientists learn more about genetic changes and their impact on the brain and behavior. Participation in the Brain Gene Registry requires participation in GenomeConnect. -
