Genes affected
ONECUT2 (HGNC:8139): (one cut homeobox 2) This gene encodes a member of the onecut family of transcription factors, which are characterized by a cut domain and an atypical homeodomain. The protein binds to specific DNA sequences and stimulates expression of target genes, including genes involved in melanocyte and hepatocyte differentiation. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2023The c.682G>A (p.A228T) alteration is located in exon 1 (coding exon 1) of the ONECUT2 gene. This alteration results from a G to A substitution at nucleotide position 682, causing the alanine (A) at amino acid position 228 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
