Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP3BP4_ModerateBP6_Moderate

The NM_001128918.3(MARK3):c.886G>C(p.Gly296Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000165 in 1,613,688 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G296S) has been classified as Uncertain significance.

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]
