Genes affected

THEM4 (HGNC:17947): (thioesterase superfamily member 4) Protein kinase B (PKB) is a major downstream target of receptor tyrosine kinases that signal via phosphatidylinositol 3-kinase. Upon cell stimulation, PKB is translocated to the plasma membrane, where it is phosphorylated in the C-terminal regulatory domain. The protein encoded by this gene negatively regulates PKB activity by inhibiting phosphorylation. Transcription of this gene is commonly downregulated in glioblastomas.

The c.226T>A (p.L76M) alteration is located in exon 2 (coding exon 2) of the THEM4 gene. This alteration results from a T to A substitution at nucleotide position 226, causing the leucine (L) at amino acid position 76 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
