Genes affected

UBE4A (HGNC:12499): (ubiquitination factor E4A) This gene encodes a member of the U-box ubiquitin ligase family. The encoded protein is involved in multiubiquitin chain assembly and plays a critical role in chromosome condensation and separation through the polyubiquitination of securin. Autoantibodies against the encoded protein may be markers for scleroderma and Crohn's disease. A pseudogene of this gene is located on the long arm of chromosome 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2011]

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=0.021088451).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000854 (13/152296) while in subpopulation AFR AF= 0.000265 (11/41574). AF 95% confidence interval is 0.000148. There are 0 homozygotes in gnomad4. There are 7 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The UBE4A c.714G>C variant is predicted to result in the amino acid substitution p.Gln238His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.020% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
