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]

Ambry Genetics

Aug 17, 2022

The c.400G>A (p.A134T) alteration is located in exon 3 (coding exon 3) of the LMAN2 gene. This alteration results from a G to A substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
