Genes affected

GRHL2 (HGNC:2799): (grainyhead like transcription factor 2) The protein encoded by this gene is a transcription factor that can act as a homodimer or as a heterodimer with either GRHL1 or GRHL3. Defects in this gene are a cause of non-syndromic sensorineural deafness autosomal dominant type 28 (DFNA28).[provided by RefSeq, Mar 2009]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 183 of the GRHL2 protein (p.Arg183Gln). This variant is present in population databases (rs142411476, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with GRHL2-related conditions. ClinVar contains an entry for this variant (Variation ID: 178378). 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 GRHL2 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

Variant classified as Uncertain Significance - Favor Benign. The p.Arg183Gln var iant in GRHL2 has been identified by our laboratory in one individual with heari ng loss, but did not segregate with the disease in an affected relative (LMM unp ublished data). It has been identified in 27/66684 European chromosomes by the E xome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs14241 1476). Computational prediction tools and conservation analysis suggest that the p.Arg183Gln variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical sign ificance of the p.Arg183Gln variant is uncertain, these data suggest that it is more likely to be benign. -
