Genes affected

PICK1 (HGNC:9394): (protein interacting with PRKCA 1) The protein encoded by this gene contains a PDZ domain, through which it interacts with protein kinase C, alpha (PRKCA). This protein may function as an adaptor that binds to and organizes the subcellular localization of a variety of membrane proteins. It has been shown to interact with multiple glutamate receptor subtypes, monoamine plasma membrane transporters, as well as non-voltage gated sodium channels, and may target PRKCA to these membrane proteins and thus regulate their distribution and function. This protein has also been found to act as an anchoring protein that specifically targets PRKCA to mitochondria in a ligand-specific manner. Three transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Apr 15, 2024

The c.873C>G (p.N291K) alteration is located in exon 12 (coding exon 11) of the PICK1 gene. This alteration results from a C to G substitution at nucleotide position 873, causing the asparagine (N) at amino acid position 291 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
