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 was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0765852).

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000376 (55/1461872) while in subpopulation AMR AF = 0.000581 (26/44718). AF 95% confidence interval is 0.000407. There are 1 homozygotes in GnomAdExome4. There are 30 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
