Genes affected

MED8 (HGNC:19971): (mediator complex subunit 8) This gene encodes a protein component of the mediator complex, which aids in transcriptional activation through interaction with RNA polymerase II and gene-specific transcription factors. The encoded protein may also function in ubiquitin ligation and protein degradation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.685C>T (p.P229S) alteration is located in exon 6 (coding exon 6) of the MED8 gene. This alteration results from a C to T substitution at nucleotide position 685, causing the proline (P) at amino acid position 229 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
