Genes affected

PBK (HGNC:18282): (PDZ binding kinase) This gene encodes a serine/threonine protein kinase related to the dual specific mitogen-activated protein kinase kinase (MAPKK) family. Evidence suggests that mitotic phosphorylation is required for its catalytic activity. The encoded protein may be involved in the activation of lymphoid cells and support testicular functions, with a suggested role in the process of spermatogenesis. Overexpression of this gene has been implicated in tumorigenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

The c.517G>A (p.V173I) alteration is located in exon 6 (coding exon 5) of the PBK gene. This alteration results from a G to A substitution at nucleotide position 517, causing the valine (V) at amino acid position 173 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
