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 -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009678006).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000808 (123/152264) while in subpopulation AFR AF= 0.00241 (100/41546). AF 95% confidence interval is 0.00202. There are 0 homozygotes in gnomad4. There are 66 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 123 AD gene.

The c.32G>A (p.R11Q) alteration is located in exon 2 (coding exon 2) of the GRHL3 gene. This alteration results from a G to A substitution at nucleotide position 32, causing the arginine (R) at amino acid position 11 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
