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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 552 of the DEAF1 protein (p.Glu552Lys). This variant is present in population databases (rs765017164, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of DEAF1-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 1375462). 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) performed at Invitae indicates that this missense variant is not expected to disrupt DEAF1 protein function with a negative predictive value of 80%. 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence variant is a single nucleotide substitution (G>A) at position 1654 of the coding sequence of the DEAF1 gene that results in a glutamic acid to lysine amino acid change at residue 552 of the DEAF1 transcription factor protein. This residue falls in the MYND zinc finger domain (UniProt). This is a previously reported variant (ClinVar 1375462) that has not been observed in individuals affected by a DEAF1-related disorder in the published literature, to our knowledge. This variant is present in 40 of 1613016 alleles (0.0025%) in the gnomAD population dataset. Bioinformatic tools are inconclusive if this amino acid change will be damaging or tolerated, and the Glu552 residue at this position is highly conserved across the vertebrate species examined. Studies examining the functional consequence of this variant have not been published, to our knowledge. At this time, there is insufficient evidence to determine if this variant is pathogenic or benign. Therefore, we consider this a variant of uncertain significance. ACMG Criteria: PM2 -
