Invitae RCV000459559 SCV000547226 uncertain significance Fanconi anemia 2019-12-23 criteria provided, single submitter clinical testing This sequence change replaces proline with serine at codon 593 of the FANCD2 protein (p.Pro593Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine. This variant is present in population databases (rs147523071, ExAC 0.1%). This variant has not been reported in the literature in individuals with FANCD2-related disease. ClinVar contains an entry for this variant (Variation ID: 134313). 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 serine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.

Lurie Children's Hospital of Chicago RCV000764454 SCV000898676 uncertain significance Fanconi anemia, complementation group D2 2018-11-07 criteria provided, single submitter clinical testing FANCD2 NM_033084.4 exon 20 p.Pro593Ser (c.1777C>T): This variant has not been reported in the literature and is present in 0.1% (184/129068) of European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/3-10103845-C-T). This variant is present in ClinVar (Variation ID:134313). This variant amino acid Serine (Ser) is present in several species including multiple primates and other mammals, and it is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
Illumina Clinical Services Laboratory,Illumina RCV000764454 SCV001306118 uncertain significance Fanconi anemia, complementation group D2 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.

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.
