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]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-16904073-G-T is Pathogenic according to our data. Variant chr10-16904073-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 522697.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

ClinVar contains an entry for this variant (Variation ID: 522697). This variant has not been reported in the literature in individuals affected with CUBN-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ser2652*) 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). For these reasons, this variant has been classified as Pathogenic. -
