Genes affected

MARK3 (HGNC:6897): (microtubule affinity regulating kinase 3) The protein encoded by this gene is activated by phosphorylation and in turn is involved in the phosphorylation of tau proteins MAP2 and MAP4. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.113G>A (p.R38Q) alteration is located in exon 2 (coding exon 2) of the MARK3 gene. This alteration results from a G to A substitution at nucleotide position 113, causing the arginine (R) at amino acid position 38 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
