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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 26, 2022 | The c.821C>A (p.T274K) alteration is located in exon 4 (coding exon 4) of the TCERG1 gene. This alteration results from a C to A substitution at nucleotide position 821, causing the threonine (T) at amino acid position 274 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
