Genes affected

MTDH (HGNC:29608): (metadherin) Enables NF-kappaB binding activity; double-stranded RNA binding activity; and transcription coactivator activity. Involved in several processes, including lipopolysaccharide-mediated signaling pathway; positive regulation of intracellular signal transduction; and regulation of transcription, DNA-templated. Located in endoplasmic reticulum; nuclear lumen; and perinuclear region of cytoplasm. Implicated in hepatocellular carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Apr 22, 2022

The c.697G>A (p.E233K) alteration is located in exon 4 (coding exon 4) of the MTDH gene. This alteration results from a G to A substitution at nucleotide position 697, causing the glutamic acid (E) at amino acid position 233 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
