Genes affected

MAPK11 (HGNC:6873): (mitogen-activated protein kinase 11) This gene encodes a member of a family of protein kinases that are involved in the integration of biochemical signals for a wide variety of cellular processes, including cell proliferation, differentiation, transcriptional regulation, and development. The encoded protein can be activated by proinflammatory cytokines and environmental stresses through phosphorylation by mitogen activated protein kinase kinases (MKKs). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.33874947).

Collection Method: clinical testing

The c.910G>T (p.A304S) alteration is located in exon 11 (coding exon 11) of the MAPK11 gene. This alteration results from a G to T substitution at nucleotide position 910, causing the alanine (A) at amino acid position 304 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
