Genes affected
INMT (HGNC:6069): (indolethylamine N-methyltransferase) N-methylation of endogenous and xenobiotic compounds is a major method by which they are degraded. This gene encodes an enzyme that N-methylates indoles such as tryptamine. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream MINDY4 (aka FAM188B) gene. In rodents and other mammals such as cetartiodactyla this gene is in the opposite orientation compared to its orientation in human and other primates and this gene appears to have been lost in carnivora and chiroptera. [provided by RefSeq, Jul 2019]
INMT-MINDY4 (HGNC:41995): (INMT-MINDY4 readthrough (NMD candidate)) This locus represents rare but naturally occurring read-through transcription between the INMT (indolethylamine N-methyltransferase) and FAM188B (family with sequence similarity 188, member B) genes on chromosome 7. The read-through transcript is unlikely to produce a protein because it is a nonsense-mediated mRNA decay (NMD) candidate based on translation from the supported INMT start codon.
