Genes affected

RICTOR (HGNC:28611): (RPTOR independent companion of MTOR complex 2) RICTOR and MTOR (FRAP1; MIM 601231) are components of a protein complex that integrates nutrient- and growth factor-derived signals to regulate cell growth (Sarbassov et al., 2004 [PubMed 15268862]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.40940318).

The c.3313C>A (p.P1105T) alteration is located in exon 31 (coding exon 31) of the RICTOR gene. This alteration results from a C to A substitution at nucleotide position 3313, causing the proline (P) at amino acid position 1105 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
