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]

Ambry Genetics

Nov 30, 2022

The c.1298C>T (p.P433L) alteration is located in exon 13 (coding exon 13) of the MARK3 gene. This alteration results from a C to T substitution at nucleotide position 1298, causing the proline (P) at amino acid position 433 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
