Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1 PM2 PM5 PP3_Strong

The ENST00000262187.10(RHEB):​c.103T>A​(p.Tyr35Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y35C) has been classified as Pathogenic.

• Frequency: Genomes: not found (cov: 32)
• Consequence: RHEB ENST00000262187.10 missense
• Clinical Significance: Likely pathogenic no assertion criteria provided P:4
• Conservation: PhyloP100: 8.67

Genes affected

RHEB (HGNC:10011): (Ras homolog, mTORC1 binding) This gene is a member of the small GTPase superfamily and encodes a lipid-anchored, cell membrane protein with five repeats of the RAS-related GTP-binding region. This protein is vital in regulation of growth and cell cycle progression due to its role in the insulin/TOR/S6K signaling pathway. The protein has GTPase activity and shuttles between a GDP-bound form and a GTP-bound form, and farnesylation of the protein is required for this activity. Three pseudogenes have been mapped, two on chromosome 10 and one on chromosome 22. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a chain GTP-binding protein Rheb (size 180) in uniprot entity RHEB_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in ENST00000262187.10
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr7-151490963-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 376516.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.982
