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]

LOC100131626 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BS1: Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0185 (17712/956032) while in subpopulation AFR AF= 0.0239 (512/21378). AF 95% confidence interval is 0.0222. There are 0 homozygotes in gnomad4_exome. There are 9006 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
