Genes affected

RRAGC (HGNC:19902): (Ras related GTP binding C) This gene encodes a member of the GTR/RAG GTP-binding protein family. The encoded protein is a monomeric guanine nucleotide-binding protein which forms a heterodimer with RRAGA and RRAGB and is primarily localized to the cytoplasm. The encoded protein promotes intracellular localization of the mTOR complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

The c.1120C>G (p.H374D) alteration is located in exon 7 (coding exon 7) of the RRAGC gene. This alteration results from a C to G substitution at nucleotide position 1120, causing the histidine (H) at amino acid position 374 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
