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]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1322175). This variant has not been reported in the literature in individuals affected with CUBN-related conditions. This variant is present in population databases (rs756614749, gnomAD 0.02%). This sequence change creates a premature translational stop signal (p.Glu3538*) in the CUBN gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CUBN are known to be pathogenic (PMID: 15024727, 22929189, 25349199, 34979989). -
