Genes affected

GSK3B (HGNC:4617): (glycogen synthase kinase 3 beta) The protein encoded by this gene is a serine-threonine kinase belonging to the glycogen synthase kinase subfamily. It is a negative regulator of glucose homeostasis and is involved in energy metabolism, inflammation, ER-stress, mitochondrial dysfunction, and apoptotic pathways. Defects in this gene have been associated with Parkinson disease and Alzheimer disease. [provided by RefSeq, Aug 2017]

GSK3B Gene-Disease associations (from GenCC):

• neurodevelopmental disorder

  Inheritance: AD Classification: DEFINITIVE Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BS2: High AC in GnomAd4 at 7 AD gene.
