Genes affected

UBQLN4 (HGNC:1237): (ubiquilin 4) Enables K48-linked polyubiquitin modification-dependent protein binding activity and identical protein binding activity. Involved in cellular response to DNA damage stimulus; negative regulation of double-strand break repair via homologous recombination; and regulation of cellular catabolic process. Located in several cellular components, including autophagosome; nucleoplasm; and site of DNA damage. Part of protein-containing complex. Colocalizes with cytosolic proteasome complex and nuclear proteasome complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.008500159).
• BP6: Variant 1-156048508-C-T is Benign according to our data. Variant chr1-156048508-C-T is described in ClinVar as [Benign]. Clinvar id is 787857.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.00864 (12580/1456718) while in subpopulation SAS AF= 0.0172 (1478/86068). AF 95% confidence interval is 0.0164. There are 81 homozygotes in gnomad4_exome. There are 6528 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 890 AD gene.
