Genes affected

MAPK3 (HGNC:6877): (mitogen-activated protein kinase 3) The protein encoded by this gene is a member of the MAP kinase family. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act in a signaling cascade that regulates various cellular processes such as proliferation, differentiation, and cell cycle progression in response to a variety of extracellular signals. This kinase is activated by upstream kinases, resulting in its translocation to the nucleus where it phosphorylates nuclear targets. Alternatively spliced transcript variants encoding different protein isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BP6: Variant 16-30116903-C-T is Benign according to our data. Variant chr16-30116903-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 710826.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.48 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00274 (3998/1461706) while in subpopulation MID AF = 0.0218 (126/5768). AF 95% confidence interval is 0.0187. There are 12 homozygotes in GnomAdExome4. There are 1993 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 418 AD gene.
