Genes affected
LMAN2 (HGNC:16986): (lectin, mannose binding 2) This gene encodes a type I transmembrane lectin that shuttles between the endoplasmic reticulum, the Golgi apparatus and the plasma membrane. The encoded protein binds high mannose type glycoproteins and may facilitate their sorting, trafficking and quality control. [provided by RefSeq, Oct 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2022The c.956C>T (p.T319M) alteration is located in exon 8 (coding exon 8) of the LMAN2 gene. This alteration results from a C to T substitution at nucleotide position 956, causing the threonine (T) at amino acid position 319 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
