Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_023935.3(DDRGK1):c.836T>C(p.Val279Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000109 in 1,461,744 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V279M) has been classified as Uncertain significance.

Genes affected

DDRGK1 (HGNC:16110): (DDRGK domain containing 1) The protein encoded by this gene interacts with components of the ubiquitin fold modifier 1 conjugation pathway and helps prevent apoptosis in ER-stressed secretory tissues. In addition, the encoded protein regulates nuclear factor-κB activity. [provided by RefSeq, Dec 2015]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). ClinVar contains an entry for this variant (Variation ID: 1471614). This variant has not been reported in the literature in individuals affected with DDRGK1-related conditions. This variant is present in population databases (rs779943089, gnomAD 0.05%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 279 of the DDRGK1 protein (p.Val279Ala). -
