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 serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 214 of the GRHL2 protein (p.Ser214Asn). This variant is present in population databases (rs199931364, gnomAD 0.01%). 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: 228733). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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

The p.Ser214Asn variant in GRHL2 has been reported in 1 individual with mild sen sorineural hearing loss (LMM data). This variant has been identified in 14/12629 2 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad .broadinstitute.org; dbSNP rs199931364). Computational prediction tools and cons ervation analysis suggest that the p.Ser214Asn variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, the clinical significance of the p.Ser214Asn variant is uncertain. ACMG/ AMP Criteria applied: PM2_Supporting, PP3 -
