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]

Ambry Genetics

Nov 08, 2021

The c.1621C>T (p.P541S) alteration is located in exon 11 (coding exon 11) of the PKN2 gene. This alteration results from a C to T substitution at nucleotide position 1621, causing the proline (P) at amino acid position 541 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
