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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2024The c.538A>G (p.T180A) alteration is located in exon 4 (coding exon 4) of the GRHL1 gene. This alteration results from a A to G substitution at nucleotide position 538, causing the threonine (T) at amino acid position 180 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
