Genes affected

TFCP2 (HGNC:11748): (transcription factor CP2) This gene encodes a transcription factor that binds the alpha-globin promoter and activates transcription of the alpha-globin gene. The encoded protein regulates erythroid gene expression, plays a role in the transcriptional switch of globin gene promoters, and it activates many other cellular and viral gene promoters. The gene product interacts with certain inflammatory response factors, and polymorphisms of this gene may be involved in the pathogenesis of Alzheimer's disease. [provided by RefSeq, Mar 2010]

The c.289A>G (p.I97V) alteration is located in exon 3 (coding exon 3) of the TFCP2 gene. This alteration results from a A to G substitution at nucleotide position 289, causing the isoleucine (I) at amino acid position 97 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
