Genes affected

LRRC51 (HGNC:55526): (leucine rich repeat containing 51) This gene belongs to the leucine-rich repeat containing family. The encoded protein contains a transmembrane domain and two leucine-rich repeat domains. Unlike in mouse and other mammals, readthrough transcription is observed in primates between this gene and the adjacent transmembrane O-methyltransferase (Tomt) gene. Previously, this locus was annotated as a single gene representing the readthrough transcripts as well as the two different transcript species that encoded different proteins. It has since been split into three genes, including the two stand-alone genes and a third gene representing the readthrough transcription. [provided by RefSeq, Feb 2022]

LRTOMT (HGNC:):

LAMTOR1 (HGNC:26068): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 1) Enables GTPase binding activity. Contributes to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Involved in several processes, including cholesterol homeostasis; positive regulation of TOR signaling; and regulation of cholesterol transport. Located in lysosome. Part of Ragulator complex.
