Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 2P and 8B. PM2BP4_StrongBS1

The NM_001081.4(CUBN):c.1951C>G(p.Arg651Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000472 in 1,613,690 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R651Q) has been classified as Uncertain significance.

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

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.020391047).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000598 (91/152194) while in subpopulation EAS AF= 0.0161 (83/5168). AF 95% confidence interval is 0.0133. There are 0 homozygotes in gnomad4. There are 54 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

clinical testing

Illumina Laboratory Services, Illumina

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
