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]

MARK3 Gene-Disease associations (from GenCC):

• visual impairment and progressive phthisis bulbi

  Inheritance: AR, Unknown Classification: LIMITED Submitted by: G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
