Genes affected

GSPT2 (HGNC:4622): (G1 to S phase transition 2) This gene encodes a GTPase that belongs to the GTP-binding elongation factor family. The encoded protein is a polypeptide release factor that complexes with eukaryotic peptide chain release factor 1 to mediate translation termination. This protein may also be involved in mRNA stability.[provided by RefSeq, Mar 2010]

Feb 22, 2023

The c.1210T>G (p.F404V) alteration is located in exon 1 (coding exon 1) of the GSPT2 gene. This alteration results from a T to G substitution at nucleotide position 1210, causing the phenylalanine (F) at amino acid position 404 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
