Genes affected

A1CF (HGNC:24086): (APOBEC1 complementation factor) Mammalian apolipoprotein B mRNA undergoes site-specific C to U deamination, which is mediated by a multi-component enzyme complex containing a minimal core composed of APOBEC-1 and a complementation factor encoded by this gene. The gene product has three non-identical RNA recognition motifs and belongs to the hnRNP R family of RNA-binding proteins. It has been proposed that this complementation factor functions as an RNA-binding subunit and docks APOBEC-1 to deaminate the upstream cytidine. Studies suggest that the protein may also be involved in other RNA editing or RNA processing events. Several transcript variants encoding a few different isoforms have been found for this gene.

ASAH2B (HGNC:23456): (N-acylsphingosine amidohydrolase 2B) Predicted to enable N-acylsphingosine amidohydrolase activity. Predicted to be involved in ceramide catabolic process; long-chain fatty acid biosynthetic process; and sphingosine biosynthetic process. Predicted to be active in extracellular region.
