Genes affected
MME (HGNC:7154): (membrane metalloendopeptidase) The protein encoded by this gene is a type II transmembrane glycoprotein and a common acute lymphocytic leukemia antigen that is an important cell surface marker in the diagnosis of human acute lymphocytic leukemia (ALL). The encoded protein is present on leukemic cells of pre-B phenotype, which represent 85% of cases of ALL. This protein is not restricted to leukemic cells, however, and is found on a variety of normal tissues. The protein is a neutral endopeptidase that cleaves peptides at the amino side of hydrophobic residues and inactivates several peptide hormones including glucagon, enkephalins, substance P, neurotensin, oxytocin, and bradykinin.

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Mar 03, 2023 | This sequence change creates a premature translational stop signal (p.Trp535*) in the MME gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MME are known to be pathogenic (PMID: 26991897). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MME-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic. - |
