Variant names:

• chr1-45829544-C-G
• rs1644889730
• NM_015112.3:c.431C>G

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_015112.3(MAST2):​c.431C>G​(p.Ser144Cys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S144Y) has been classified as Uncertain significance.

• Consequence: MAST2 NM_015112.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.55
• Publications: 0 publications found

Genes affected

MAST2 (HGNC:19035): (microtubule associated serine/threonine kinase 2) Enables phosphatase binding activity. Predicted to be involved in several processes, including peptidyl-serine phosphorylation; regulation of interleukin-12 production; and spermatid differentiation. Predicted to be located in cytoplasm and plasma membrane. Predicted to be active in microtubule cytoskeleton. [provided by Alliance of Genome Resources, Apr 2022]

MAST2 Gene-Disease associations (from GenCC):

• thrombotic disease

  Inheritance: AD Classification: LIMITED Submitted by: ClinGen
