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 GeneticsOct 03, 2022The c.991G>A (p.A331T) alteration is located in exon 7 (coding exon 7) of the GRHL1 gene. This alteration results from a G to A substitution at nucleotide position 991, causing the alanine (A) at amino acid position 331 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
