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]

DEAF1 links:

EPS8L2 (HGNC:21296): (EPS8 signaling adaptor L2) This gene encodes a member of the EPS8 gene family. The encoded protein, like other members of the family, is thought to link growth factor stimulation to actin organization, generating functional redundancy in the pathways that regulate actin cytoskeletal remodeling.

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 87 of the DEAF1 protein (p.Asp87Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DEAF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1373180). 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. 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. -
