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]

Ambry Genetics

Aug 13, 2021

The c.251A>G (p.K84R) alteration is located in exon 2 (coding exon 2) of the MAST2 gene. This alteration results from a A to G substitution at nucleotide position 251, causing the lysine (K) at amino acid position 84 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
