• Conservation: PhyloP100: 4.83

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 Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.968
• PP5: Variant 10-17019886-G-C is Pathogenic according to our data. Variant chr10-17019886-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 56338.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr10-17019886-G-C is described in Lovd as [Likely_pathogenic].
