Genes affected

EEF1D (HGNC:3211): (eukaryotic translation elongation factor 1 delta) This gene encodes a subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This subunit, delta, functions as guanine nucleotide exchange factor. It is reported that following HIV-1 infection, this subunit interacts with HIV-1 Tat. This interaction results in repression of translation of host cell proteins and enhanced translation of viral proteins. Several alternatively spliced transcript variants encoding multiple isoforms have been found for this gene. Related pseudogenes have been defined on chromosomes 1, 6, 7, 9, 11, 13, 17, 19.[provided by RefSeq, Aug 2010]

The c.1753C>T (p.R585C) alteration is located in exon 9 (coding exon 7) of the EEF1D gene. This alteration results from a C to T substitution at nucleotide position 1753, causing the arginine (R) at amino acid position 585 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

(N) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (18 heterozygotes, 0 homozygotes). (P) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (45 heterozygotes, 0 homozygotes). (N) 0501 - Missense variant consistently predicted to be damaging by multiple in-silico tools or highly conserved with a major amino acid change. (P) 0600 - Variant is located in an annotated domain or motif (EF-1 guanine nucleotide exchange domain; NCBI, Decipher, PDB). (N) 0705 - No comparable variants have previous evidence for pathogenicity. (N) 0807 - Variant has not previously been reported in a clinical context. (N) 0905 - No segregation evidence has been identified for this variant. (N) 1007 - No published functional evidence has been identified for this variant.
