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 Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 24, 2020This variant has been observed in an individual with clinical features of Imerslund-Gräsbeck syndrome (PMID: 22929189). ClinVar contains an entry for this variant (Variation ID: 56331). Loss-of-function variants in CUBN are known to be pathogenic (PMID: 15024727, 22929189). For these reasons, this variant has been classified as Pathogenic. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Cys891*) in the CUBN gene. It is expected to result in an absent or disrupted protein product. -
