Genes affected
EIF2B4 (HGNC:3260): (eukaryotic translation initiation factor 2B subunit delta) Eukaryotic initiation factor 2B (EIF2B), which is necessary for protein synthesis, is a GTP exchange factor composed of five different subunits. The protein encoded by this gene is the fourth, or delta, subunit. Defects in this gene are a cause of leukoencephalopathy with vanishing white matter (VWM) and ovarioleukodystrophy. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.299G>T (p.R100L) alteration is located in exon 4 (coding exon 4) of the EIF2B4 gene. This alteration results from a G to T substitution at nucleotide position 299, causing the arginine (R) at amino acid position 100 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
