Genes affected

MARK2 (HGNC:3332): (microtubule affinity regulating kinase 2) This gene encodes a member of the Par-1 family of serine/threonine protein kinases. The protein is an important regulator of cell polarity in epithelial and neuronal cells, and also controls the stability of microtubules through phosphorylation and inactivation of several microtubule-associating proteins. The protein localizes to cell membranes. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2009]

Nov 22, 2023

The c.156C>G (p.N52K) alteration is located in exon 2 (coding exon 2) of the MARK2 gene. This alteration results from a C to G substitution at nucleotide position 156, causing the asparagine (N) at amino acid position 52 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
