Genes affected

STK26 (HGNC:18174): (serine/threonine kinase 26) The product of this gene is a member of the GCK group III family of kinases, which are a subset of the Ste20-like kinases. The encoded protein contains an amino-terminal kinase domain, and a carboxy-terminal regulatory domain that mediates homodimerization. The protein kinase localizes to the Golgi apparatus and is specifically activated by binding to the Golgi matrix protein GM130. It is also cleaved by caspase-3 in vitro, and may function in the apoptotic pathway. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

Ambry Genetics

Apr 28, 2022

The c.1008G>C (p.K336N) alteration is located in exon 9 (coding exon 8) of the STK26 gene. This alteration results from a G to C substitution at nucleotide position 1008, causing the lysine (K) at amino acid position 336 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
