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:25033): (leucine rich transmembrane and O-methyltransferase domain containing) This locus represents naturally occurring readthrough transcription between the neighboring LRRC51 (leucine-rich repeat containing 51) and TOMT (transmembrane O-methyltransferase) genes on chromosome 11. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. Multiple reports implicate mutations in this gene in nonsyndromic deafness.[provided by RefSeq, Feb 2021]
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.
