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

Verdict is Benign. Variant got -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 [Likely_benign]. Clinvar id 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. gnomad4_exome 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 gnomad4_exome. There are 1993 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 418 AD gene.
