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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.23).
BP6
Variant 1-24334642-C-A is Benign according to our data. Variant chr1-24334642-C-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 932032.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000302 (46/152104) while in subpopulation AMR AF= 0.000785 (12/15278). AF 95% confidence interval is 0.000452. There are 0 homozygotes in gnomad4. There are 19 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAd4 at 46 AD gene.
