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]

Collection Method: clinical testing

The c.74G>T (p.R25L) alteration is located in exon 1 (coding exon 1) of the TFDP3 gene. This alteration results from a G to T substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
