Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV001251508 SCV001427154 uncertain significance Imerslund-Grasbeck syndrome type 1 2018-11-21 criteria provided, single submitter clinical testing A heterozygous missense variant, NM_001081.3(CUBN):c.2839G>T, has been identified in exon 21 of 67 of the CUBN gene. The variant is predicted to result in a major amino acid change from glycine to cysteine at position 947 of the protein (NP_001072.2(CUBN):p.(Gly947Cys)). The glycine residue at this position has moderate conservation (100 vertebrates, UCSC), and is located within the heterodimerization interface of the CUB 5 domain. In silico predictions for this variant are consistently pathogenic (Polyphen, SIFT, CADD, Mutation Taster). The variant is absent in population databases (gnomAD, dbSNP, 1000G) and has not been previously reported in clinical cases. Based on the information available at the time of curation, this variant has been classified as a VARIANT of UNCERTAIN SIGNIFICANCE (VUS).
