Genes affected

PKN2 (HGNC:9406): (protein kinase N2) Enables RNA polymerase binding activity; histone deacetylase binding activity; and protein serine/threonine kinase activity. Involved in several processes, including apical junction assembly; positive regulation of cell cycle; and positive regulation of viral genome replication. Located in several cellular components, including cleavage furrow; cytoskeleton; and midbody. [provided by Alliance of Genome Resources, Apr 2022]

The c.1142G>A (p.R381Q) alteration is located in exon 7 (coding exon 7) of the PKN2 gene. This alteration results from a G to A substitution at nucleotide position 1142, causing the arginine (R) at amino acid position 381 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
