Genes affected

KMT2E (HGNC:18541): (lysine methyltransferase 2E (inactive)) This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a protein with an N-terminal PHD zinc finger and a central SET domain. Overexpression of the protein inhibits cell cycle progression. Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]

KMT2E links:

SRPK2 (HGNC:11306): (SRSF protein kinase 2) Enables ATP binding activity; magnesium ion binding activity; and protein serine/threonine kinase activity. Involved in several processes, including nucleic acid metabolic process; peptidyl-serine phosphorylation; and regulation of viral genome replication. Located in chromatin; cytosol; and nuclear lumen.

Ambry Genetics

Jan 26, 2022

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
