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]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-63895601-A-AAG is Pathogenic according to our data. Variant chr11-63895601-A-AAG is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3253644.Status of the report is no_assertion_criteria_provided, 0 stars.
