Illumina Laboratory Services, Illumina RCV001117939 SCV001276184 uncertain significance Congenital dyserythropoietic anemia, type I 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Invitae RCV002558164 SCV003257803 uncertain significance not provided 2022-10-15 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 1045 of the CDAN1 protein (p.Asp1045Glu). This variant is present in population databases (rs146289653, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with CDAN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 886001). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002558163 SCV003657993 likely benign Inborn genetic diseases 2021-08-02 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
