Genes affected

LMAN2L (HGNC:19263): (lectin, mannose binding 2 like) This gene encodes a protein belonging to the L-type lectin group of type 1 membrane proteins, which function in the mammalian early secretory pathway. These proteins contain luminal carbohydrate recognition domains, which display homology to leguminous lectins. Unlike other proteins of the group, which cycle in the early secretory pathway and are predominantly associated with post endoplasmic reticulum membranes, the protein encoded by this gene is a non-cycling resident protein of the ER, where it functions as a cargo receptor for glycoproteins. It is proposed to regulate exchange of folded proteins for transport to the Golgi and exchange of misfolded glycoproteins for transport to the ubiquitin-proteasome pathway.

Collection Method: clinical testing

The c.679C>T (p.R227C) alteration is located in exon 6 (coding exon 6) of the LMAN2L gene. This alteration results from a C to T substitution at nucleotide position 679, causing the arginine (R) at amino acid position 227 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
