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]

Dec 14, 2022

The c.952C>G (p.R318G) alteration is located in exon 9 (coding exon 9) of the LMAN1L gene. This alteration results from a C to G substitution at nucleotide position 952, causing the arginine (R) at amino acid position 318 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
