Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4_StrongBS1_Supporting

The NM_175748.4(UBR7):c.23C>A(p.Ala8Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000308 in 1,557,506 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. 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. A8T) has been classified as Uncertain significance.

Genes affected

UBR7 (HGNC:20344): (ubiquitin protein ligase E3 component n-recognin 7) This gene encodes a UBR box-containing protein that belongs to the E3 ubiquitin ligase family. The protein also contains a plant homeodomain (PHD) in the C-terminus. In mammals, the encoded protein recognizes N-degrons, the destabilizing N-terminal residues of short-lived proteins, which results in ubiquitinylation, and proteolysis via the proteasome.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.051255733).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000171 (26/152362) while in subpopulation AFR AF= 0.000601 (25/41598). AF 95% confidence interval is 0.000418. There are 0 homozygotes in gnomad4. There are 14 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Ambry Genetics

Dec 28, 2022

The c.23C>A (p.A8D) alteration is located in exon 1 (coding exon 1) of the UBR7 gene. This alteration results from a C to A substitution at nucleotide position 23, causing the alanine (A) at amino acid position 8 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
