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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 27, 2022 | The c.692T>A (p.V231D) alteration is located in exon 6 (coding exon 6) of the LMAN1L gene. This alteration results from a T to A substitution at nucleotide position 692, causing the valine (V) at amino acid position 231 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
