Genes affected
CUBN (HGNC:2548): (cubilin) Cubilin (CUBN) acts as a receptor for intrinsic factor-vitamin B12 complexes. The role of receptor is supported by the presence of 27 CUB domains. Cubulin is located within the epithelium of intestine and kidney. Mutations in CUBN may play a role in autosomal recessive megaloblastic anemia. [provided by RefSeq, Jul 2008]

Imerslund-Grasbeck syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 13, 2018 | This sequence change replaces proline with arginine at codon 1299 of the CUBN protein (p.Pro1299Arg). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and arginine. This variant is present in population databases (rs752570169, ExAC 0.009%). This variant has not been reported in the literature in individuals with CUBN-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
