Genes affected

RPTOR (HGNC:30287): (regulatory associated protein of MTOR complex 1) This gene encodes a component of a signaling pathway that regulates cell growth in response to nutrient and insulin levels. The encoded protein forms a stoichiometric complex with the mTOR kinase, and also associates with eukaryotic initiation factor 4E-binding protein-1 and ribosomal protein S6 kinase. The protein positively regulates the downstream effector ribosomal protein S6 kinase, and negatively regulates the mTOR kinase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

Ambry Genetics

Apr 25, 2023

The c.1982A>T (p.K661M) alteration is located in exon 17 (coding exon 17) of the RPTOR gene. This alteration results from a A to T substitution at nucleotide position 1982, causing the lysine (K) at amino acid position 661 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
