Genes affected

EIF3H (HGNC:3273): (eukaryotic translation initiation factor 3 subunit H) Enables deubiquitinase activity. Contributes to translation initiation factor activity. Involved in negative regulation of proteasomal ubiquitin-dependent protein catabolic process and translational initiation. Located in extracellular exosome and membrane. Part of eukaryotic translation initiation factor 3 complex. Implicated in breast cancer; prostate cancer; and prostate carcinoma. Biomarker of prostate cancer.

The c.340C>G (p.H114D) alteration is located in exon 3 (coding exon 3) of the EIF3H gene. This alteration results from a C to G substitution at nucleotide position 340, causing the histidine (H) at amino acid position 114 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
