ClinVar contains an entry for this variant (Variation ID: 915957). This missense change has been observed in individual(s) with autosomal recessive DEAF1-related conditions (PMID: 30923367). It has also been observed to segregate with disease in related individuals. This variant has been reported in individual(s) with autosomal dominant DEAF1-related conditions (PMID: 32094338); however, the role of the variant in this condition is currently unclear. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 224 of the DEAF1 protein (p.Arg224Gln). 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. 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. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on DEAF1 function (PMID: 30923367).
