Genes affected
MTOR (HGNC:3942): (mechanistic target of rapamycin kinase) The protein encoded by this gene belongs to a family of phosphatidylinositol kinase-related kinases. These kinases mediate cellular responses to stresses such as DNA damage and nutrient deprivation. This kinase is a component of two distinct complexes, mTORC1, which controls protein synthesis, cell growth and proliferation, and mTORC2, which is a regulator of the actin cytoskeleton, and promotes cell survival and cell cycle progression. This protein acts as the target for the cell-cycle arrest and immunosuppressive effects of the FKBP12-rapamycin complex. Inhibitors of mTOR are used in organ transplants as immunosuppressants, and are being evaluated for their therapeutic potential in SARS-CoV-2 infections. Mutations in this gene are associated with Smith-Kingsmore syndrome and somatic focal cortical dysplasia type II. The ANGPTL7 gene is located in an intron of this gene.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MTOR. . Gene score misZ 7.0206 (greater than the threshold 3.09). Trascript score misZ 9.4864 (greater than threshold 3.09). GenCC has associacion of gene with macrocephaly-intellectual disability-neurodevelopmental disorder-small thorax syndrome, overgrowth syndrome and/or cerebral malformations due to abnormalities in MTOR pathway genes.
BP4
Computational evidence support a benign effect (MetaRNN=0.035728008).
BP6
Variant 1-11253848-C-A is Benign according to our data. Variant chr1-11253848-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 240082.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000328 (5/152208) while in subpopulation AMR AF= 0.000327 (5/15278). AF 95% confidence interval is 0.000129. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 5 AD gene.
