Variant summary

Our verdict is Benign. Variant got -16 ACMG points: 1P and 17B. PP2BP4BP6_Very_StrongBS1BS2

The NM_004958.4(MTOR):c.4941T>G(p.His1647Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000483 in 1,614,188 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. 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. H1647R) 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

Classification made for transcript

Verdict is Benign. Variant got -16 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=0.37216938).

BP6

Variant 1-11139590-A-C is Benign according to our data. Variant chr1-11139590-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 408298.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00025 (38/152294) while in subpopulation NFE AF= 0.000529 (36/68024).
