Genes affected

CMBL (HGNC:25090): (carboxymethylenebutenolidase homolog) CMBL (EC 3.1.1.45) is a cysteine hydrolase of the dienelactone hydrolase family that is highly expressed in liver cytosol. CMBL preferentially cleaves cyclic esters, and it activates medoxomil-ester prodrugs in which the medoxomil moiety is linked to an oxygen atom (Ishizuka et al., 2010 [PubMed 20177059]).[supplied by OMIM, Apr 2010]

Ambry Genetics

Nov 08, 2022

The c.302G>T (p.R101I) alteration is located in exon 3 (coding exon 2) of the CMBL gene. This alteration results from a G to T substitution at nucleotide position 302, causing the arginine (R) at amino acid position 101 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
