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]

The c.373A>G (p.I125V) alteration is located in exon 1 (coding exon 1) of the ONECUT2 gene. This alteration results from a A to G substitution at nucleotide position 373, causing the isoleucine (I) at amino acid position 125 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
