Genes affected

UNC93B1 (HGNC:13481): (unc-93 homolog B1, TLR signaling regulator) This gene encodes a protein that is involved in innate and adaptive immune response by regulating toll-like receptor signaling. The encoded protein traffics nucleotide sensing toll-like receptors to the endolysosome from the endoplasmic reticulum. Deficiency of the encoded protein has been associated with herpes simplex encephalitis. [provided by RefSeq, Feb 2014]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BP6: Variant 11-67991567-T-C is Benign according to our data. Variant chr11-67991567-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 794064.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-2.47 with no splicing effect.
