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]

The c.100C>T (p.P34S) alteration is located in exon 1 (coding exon 1) of the MAST2 gene. This alteration results from a C to T substitution at nucleotide position 100, causing the proline (P) at amino acid position 34 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
