Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 2P and 10B. PP2 PP3 BP6_Moderate BS1 BS2

The NM_004958.4(MTOR):c.931C>T(p.Arg311Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000223 in 1,614,018 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R311H) has been classified as Benign.

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

Verdict is Benign. Variant got -8 ACMG points.

• PP2: Missense variant where missense usually causes diseases, MTOR
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.83
• BP6: Variant 1-11248004-G-A is Benign according to our data. Variant chr1-11248004-G-A is described in ClinVar as [Benign]. Clinvar id is 408302.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000131 (2/152158) while in subpopulation SAS AF= 0.000415 (2/4820). AF 95% confidence interval is 0.000073. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAdExome at 10 AD gene.
