Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_001130053.5(EEF1D):c.1924G>A(p.Ala642Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000092 in 1,565,892 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★).
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]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.1924G>A (p.A642T) alteration is located in exon 10 (coding exon 8) of the EEF1D gene. This alteration results from a G to A substitution at nucleotide position 1924, causing the alanine (A) at amino acid position 642 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
