Genes affected

STPG1 (HGNC:28070): (sperm tail PG-rich repeat containing 1) Involved in positive regulation of apoptotic process and positive regulation of mitochondrial membrane permeability involved in apoptotic process. Predicted to be located in mitochondrion and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

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 Gene-Disease associations (from GenCC):

• van der Woude syndrome 2

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, G2P
• van der Woude syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BP6: Variant 1-24364647-T-C is Benign according to our data. Variant chr1-24364647-T-C is described in ClinVar as Benign. ClinVar VariationId is 1272581.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.322 is higher than 0.05.
