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

Apr 23, 2024

The c.1091C>T (p.T364I) alteration is located in exon 7 (coding exon 7) of the PKN2 gene. This alteration results from a C to T substitution at nucleotide position 1091, causing the threonine (T) at amino acid position 364 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
