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]

RFKP3 (HGNC:56487): (RFK pseudogene 3)

ENSG00000288662 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.64).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.163 is higher than 0.05.
