Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.
The NM_024915.4(GRHL2):c.685C>T(p.Arg229Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000109 in 1,461,484 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R229Q) has been classified as Uncertain significance.

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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | May 05, 2016 | The p.Arg229Trp variant in GRHL2 has not been previously reported in individuals with hearing loss, but has been identified in 1/16506 South Asian chromosomes a nd 1/11564 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http:// exac.broadinstitute.org; dbSNP rs766515922). Although this variant has been seen in the general population, its frequency is not high enough to rule out a patho genic role. Computational prediction tools and conservation analysis do not prov ide strong support for or against an impact to the protein. In summary, the clin ical significance of the p.Arg229Trp variant is uncertain. - |
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 02, 2022 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 504944). This variant has not been reported in the literature in individuals affected with GRHL2-related conditions. This variant is present in population databases (rs766515922, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 229 of the GRHL2 protein (p.Arg229Trp). - |
