Genes affected

UBR4 (HGNC:30313): (ubiquitin protein ligase E3 component n-recognin 4) The protein encoded by this gene is an E3 ubiquitin-protein ligase that interacts with the retinoblastoma-associated protein in the nucleus and with calcium-bound calmodulin in the cytoplasm. The encoded protein appears to be a cytoskeletal component in the cytoplasm and part of the chromatin scaffold in the nucleus. In addition, this protein is a target of the human papillomavirus type 16 E7 oncoprotein. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.57).
• BP6: Variant 1-19078075-G-C is Benign according to our data. Variant chr1-19078075-G-C is described in ClinVar as [Benign]. Clinvar id is 777888.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00707 (1077/152234) while in subpopulation AFR AF= 0.0231 (961/41544). AF 95% confidence interval is 0.0219. There are 18 homozygotes in gnomad4. There are 536 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1077 AD gene.
