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:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 226 of the DEAF1 protein (p.Arg226Trp). This variant is present in population databases (rs587777623, gnomAD 0.0009%). This missense change has been observed in individuals with autosomal recessive DEAF1-related conditions (PMID: 24668509, 26834045). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 143989). 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 expected to disrupt DEAF1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change does not substantially affect DEAF1 function (PMID: 28940898). For these reasons, this variant has been classified as Pathogenic. -
