Genes affected

EEFSEC (HGNC:24614): (eukaryotic elongation factor, selenocysteine-tRNA specific) Predicted to enable translation elongation factor activity. Predicted to be involved in selenocysteine incorporation. Predicted to be located in cytoplasm and nucleus. Predicted to be part of ribonucleoprotein complex. [provided by Alliance of Genome Resources, Apr 2022]

EEFSEC links:

RUVBL1 (HGNC:10474): (RuvB like AAA ATPase 1) This gene encodes a protein that has both DNA-dependent ATPase and DNA helicase activities and belongs to the ATPases associated with diverse cellular activities (AAA+) protein family. The encoded protein associates with several multisubunit transcriptional complexes and with protein complexes involved in both ATP-dependent remodeling and histone modification. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.187C>T (p.R63C) alteration is located in exon 1 (coding exon 1) of the EEFSEC gene. This alteration results from a C to T substitution at nucleotide position 187, causing the arginine (R) at amino acid position 63 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
