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.

Variant summary: KMT2E c.4040C>G (p.Thr1347Ser) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 251260 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.4040C>G in individuals affected with O'Donnell-Luria-Rodan Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 2055468). Based on the evidence outlined above, the variant was classified as uncertain significance. -
