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.

Collection Method:clinical testing

The c.947C>T (p.S316L) alteration is located in exon 7 (coding exon 7) of the EIF3H gene. This alteration results from a C to T substitution at nucleotide position 947, causing the serine (S) at amino acid position 316 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
