Genes affected

GRHL3 (HGNC:25839): (grainyhead like transcription factor 3) This gene encodes a member of the grainyhead family of transcription factors. The encoded protein may function as a transcription factor during development, and has been shown to stimulate migration of endothelial cells. Multiple transcript variants encoding distinct isoforms have been identified for this gene.[provided by RefSeq, Aug 2010]

GRHL3-AS1 (HGNC:41119): (GRHL3 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 1-24319897-C-A is Benign according to our data. Variant chr1-24319897-C-A is described in ClinVar as [Benign]. Clinvar id is 1280059.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0621 is higher than 0.05.
