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.97G>A (p.V33M) alteration is located in exon 1 (coding exon 1) of the KBTBD12 gene. This alteration results from a G to A substitution at nucleotide position 97, causing the valine (V) at amino acid position 33 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
