Genes affected
MAP3K20 (HGNC:17797): (mitogen-activated protein kinase kinase kinase 20) This gene is a member of the MAPKKK family of signal transduction molecules and encodes a protein with an N-terminal kinase catalytic domain, followed by a leucine zipper motif and a sterile-alpha motif (SAM). This magnesium-binding protein forms homodimers and is located in the cytoplasm. The protein mediates gamma radiation signaling leading to cell cycle arrest and activity of this protein plays a role in cell cycle checkpoint regulation in cells. The protein also has pro-apoptotic activity. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 26, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the effect of this variant on mRNA splicing is currently unknown. This variant has not been reported in the literature in individuals affected with MAP3K20-related conditions. This variant is present in population databases (rs149230384, gnomAD 0.007%). This sequence change affects codon 4 of the MAP3K20 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the MAP3K20 protein. -
