Genes affected

MGLL (HGNC:17038): (monoglyceride lipase) This gene encodes a serine hydrolase of the AB hydrolase superfamily that catalyzes the conversion of monoacylglycerides to free fatty acids and glycerol. The encoded protein plays a critical role in several physiological processes including pain and nociperception through hydrolysis of the endocannabinoid 2-arachidonoylglycerol. Expression of this gene may play a role in cancer tumorigenesis and metastasis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.748C>T (p.R250C) alteration is located in exon 7 (coding exon 7) of the MGLL gene. This alteration results from a C to T substitution at nucleotide position 748, causing the arginine (R) at amino acid position 250 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
