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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.08176586).
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000499 (73/1461824) while in subpopulation EAS AF = 0.00068 (27/39700). AF 95% confidence interval is 0.00048. There are 1 homozygotes in GnomAdExome4. There are 33 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
