Genes affected
SLC46A1 (HGNC:30521): (solute carrier family 46 member 1) This gene encodes a transmembrane proton-coupled folate transporter protein that facilitates the movement of folate and antifolate substrates across cell membranes, optimally in acidic pH environments. This protein is also expressed in the brain and choroid plexus where it transports folates into the central nervous system. This protein further functions as a heme transporter in duodenal enterocytes, and potentially in other tissues like liver and kidney. Its localization to the apical membrane or cytoplasm of intestinal cells is modulated by dietary iron levels. Mutations in this gene are associated with autosomal recessive hereditary folate malabsorption disease. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2013]
SARM1 (HGNC:17074): (sterile alpha and TIR motif containing 1) Enables NAD+ nucleotidase, cyclic ADP-ribose generating and identical protein binding activity. Involved in NAD catabolic process; positive regulation of neuron death; and response to axon injury. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
