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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1305169). This variant has not been reported in the literature in individuals affected with MME-related conditions. This variant is present in population databases (rs199935778, gnomAD 0.009%). This sequence change replaces proline, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 16 of the MME protein (p.Pro16Gln). -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.47C>A (p.P16Q) alteration is located in exon 2 (coding exon 1) of the MME gene. This alteration results from a C to A substitution at nucleotide position 47, causing the proline (P) at amino acid position 16 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
