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]

GRHL2-DT (HGNC:):

GRHL2-DT (HGNC:55466): (GRHL2 divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.29).
• BP6: Variant 8-101492804-C-G is Benign according to our data. Variant chr8-101492804-C-G is described in ClinVar as Likely_benign. ClinVar VariationId is 3680854.Status of the report is criteria_provided_single_submitter, 1 stars.
