Genes affected

DIRAS3 (HGNC:687): (DIRAS family GTPase 3) This gene encodes a member of the ras superfamily. This gene is imprinted gene with monoallelic expression of the paternal allele which is associated with growth suppression. The encoded protein acts as a tumor suppressor whose function is abrogated in many ovarian and breast cancers. This protein may also play a role autophagy in certain cancer cells by regulating the autophagosome initiation complex. [provided by RefSeq, Nov 2015]

The c.356C>G (p.T119S) alteration is located in exon 2 (coding exon 1) of the DIRAS3 gene. This alteration results from a C to G substitution at nucleotide position 356, causing the threonine (T) at amino acid position 119 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
