Genes affected

LGI1 (HGNC:6572): (leucine rich glioma inactivated 1) This gene encodes a member of the secreted leucine-rich repeat (LRR) superfamily and shares homology with members of the SLIT protein family. The encoded protein may regulate the activity of voltage-gated potassium channels and may be involved in neuronal growth regulation and cell survival. This gene is rearranged as a result of translocations in glioblastoma cell lines, and it is frequently down-regulated or rearranged in malignant gliomas. Mutations in this gene result in autosomal dominant lateral temporal epilepsy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), LGI1. . Gene score misZ 2.7809 (greater than the threshold 3.09). Trascript score misZ 3.4769 (greater than threshold 3.09). GenCC has associacion of gene with epilepsy, familial temporal lobe, 1, autosomal dominant epilepsy with auditory features.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.976
• PP5: Variant 10-93793207-T-C is Pathogenic according to our data. Variant chr10-93793207-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 5437.Status of the report is no_assertion_criteria_provided, 0 stars.
