Genes affected

PPP1R1B (HGNC:9287): (protein phosphatase 1 regulatory inhibitor subunit 1B) This gene encodes a bifunctional signal transduction molecule. Dopaminergic and glutamatergic receptor stimulation regulates its phosphorylation and function as a kinase or phosphatase inhibitor. As a target for dopamine, this gene may serve as a therapeutic target for neurologic and psychiatric disorders. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.310G>A (p.E104K) alteration is located in exon 5 (coding exon 5) of the PPP1R1B gene. This alteration results from a G to A substitution at nucleotide position 310, causing the glutamic acid (E) at amino acid position 104 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
