Genes affected

TFDP3 (HGNC:24603): (transcription factor Dp family member 3) This gene encodes a member of the DP family of transcription factors. These factors heterodimerize with E2F proteins to enhance their DNA-binding activity and promote transcription from E2F target genes. This protein functions as a negative regulator and inhibits the DNA binding and transcriptional activities of E2F factors.[provided by RefSeq, May 2010]

The c.751G>A (p.V251I) alteration is located in exon 1 (coding exon 1) of the TFDP3 gene. This alteration results from a G to A substitution at nucleotide position 751, causing the valine (V) at amino acid position 251 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
