Genes affected

POU2F3 (HGNC:19864): (POU class 2 homeobox 3) This gene encodes a member of the POU domain family of transcription factors. POU domain transcription factors bind to a specific octamer DNA motif and regulate cell type-specific differentiation pathways. The encoded protein is primarily expressed in the epidermis, and plays a critical role in keratinocyte proliferation and differentiation. The encoded protein is also a candidate tumor suppressor protein, and aberrant promoter methylation of this gene may play a role in cervical cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

The c.220G>A (p.G74R) alteration is located in exon 4 (coding exon 4) of the POU2F3 gene. This alteration results from a G to A substitution at nucleotide position 220, causing the glycine (G) at amino acid position 74 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
