Genes affected

EIF3K (HGNC:24656): (eukaryotic translation initiation factor 3 subunit K) The 700-kD eukaryotic translation initiation factor-3 (eIF3) is the largest eIF and contains at least 12 subunits, including EIF2S12. eIF3 plays an essential role in translation by binding directly to the 40S ribosomal subunit and promoting formation of the 40S preinitiation complex (Mayeur et al., 2003 [PubMed 14519125]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.644C>T (p.A215V) alteration is located in exon 8 (coding exon 8) of the EIF3K gene. This alteration results from a C to T substitution at nucleotide position 644, causing the alanine (A) at amino acid position 215 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
