Genes affected

GRHL1 (HGNC:17923): (grainyhead like transcription factor 1) This gene encodes a member of the grainyhead family of transcription factors. The encoded protein can exist as a homodimer or can form heterodimers with sister-of-mammalian grainyhead or brother-of-mammalian grainyhead. This protein functions as a transcription factor during development. [provided by RefSeq, Jun 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.891C>G (p.I297M) alteration is located in exon 6 (coding exon 6) of the GRHL1 gene. This alteration results from a C to G substitution at nucleotide position 891, causing the isoleucine (I) at amino acid position 297 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
