Genes affected

EEF1B2 (HGNC:3208): (eukaryotic translation elongation factor 1 beta 2) This gene encodes a translation elongation factor. The protein is a guanine nucleotide exchange factor involved in the transfer of aminoacylated tRNAs to the ribosome. Alternative splicing results in three transcript variants which differ only in the 5' UTR. [provided by RefSeq, Jul 2008]

The c.335G>A (p.S112N) alteration is located in exon 4 (coding exon 4) of the EEF1B2 gene. This alteration results from a G to A substitution at nucleotide position 335, causing the serine (S) at amino acid position 112 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
