Position:

• chr11-67991615-GG-CT

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 2P and 8B. PM2 BP6_Very_Strong

The NM_030930.4(UNC93B1):​c.1724_1725delinsAG​(p.Pro575Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P575H) has been classified as Likely benign.

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 -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 11-67991615-GG-CT is Benign according to our data. Variant chr11-67991615-GG-CT is described in ClinVar as [Likely_benign]. Clinvar id is 470494.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
