Genes affected
LMAN1L (HGNC:6632): (lectin, mannose binding 1 like) This gene encodes a mannose-binding type 1 transmembrane protein that contains an N-terminal lectin-like carbohydrate recognition domain. The encoded protein is similar in structure to lectins found in leguminous plants. This lectin is thought to transport newly synthesized glycoproteins from the endoplasmic reticulum (ER) to the ER-Golgi intermediate compartment. [provided by RefSeq, Jan 2017]
