Genes affected

AKT2 (HGNC:392): (AKT serine/threonine kinase 2) This gene is a putative oncogene encoding a protein belonging to a subfamily of serine/threonine kinases containing SH2-like (Src homology 2-like) domains, which is involved in signaling pathways. The gene serves as an oncogene in the tumorigenesis of cancer cells For example, its overexpression contributes to the malignant phenotype of a subset of human ductal pancreatic cancers. The encoded protein is a general protein kinase capable of phophorylating several known proteins, and has also been implicated in insulin signaling. [provided by RefSeq, Nov 2019]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), AKT2. . Gene score misZ 2.4133 (greater than the threshold 3.09). Trascript score misZ 3.4177 (greater than threshold 3.09). GenCC has associacion of gene with AKT2-related familial partial lipodystrophy, type 2 diabetes mellitus, diabetes mellitus, noninsulin-dependent, hypoinsulinemic hypoglycemia and body hemihypertrophy.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.788

Ambry Genetics

Nov 23, 2020

The c.1186G>C (p.G396R) alteration is located in exon 12 (coding exon 11) of the AKT2 gene. This alteration results from a G to C substitution at nucleotide position 1186, causing the glycine (G) at amino acid position 396 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
