Genes affected

TCERG1 (HGNC:15630): (transcription elongation regulator 1) This gene encodes a nuclear protein that regulates transcriptional elongation and pre-mRNA splicing. The encoded protein interacts with the hyperphosphorylated C-terminal domain of RNA polymerase II via multiple FF domains, and with the pre-mRNA splicing factor SF1 via a WW domain. Alternative splicing results in multiple transcripts variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.734C>T (p.A245V) alteration is located in exon 4 (coding exon 4) of the TCERG1 gene. This alteration results from a C to T substitution at nucleotide position 734, causing the alanine (A) at amino acid position 245 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
