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

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

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.
BP4
Computational evidence support a benign effect (MetaRNN=0.2822157).
BP6
Variant 10-93793250-T-A is Benign according to our data. Variant chr10-93793250-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 408591.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000525 (8/152242) while in subpopulation AMR AF= 0.000523 (8/15288). AF 95% confidence interval is 0.00026. There are 0 homozygotes in gnomad4. There are 0 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 8 AD gene.
