Genes affected

FANCD2 (HGNC:3585): (FA complementation group D2) The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1 (also called BRCA2), FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ (also called BRIP1), FANCL, FANCM and FANCN (also called PALB2). The previously defined group FANCH is the same as FANCA. Fanconi anemia is a genetically heterogeneous recessive disorder characterized by cytogenetic instability, hypersensitivity to DNA crosslinking agents, increased chromosomal breakage, and defective DNA repair. The members of the Fanconi anemia complementation group do not share sequence similarity; they are related by their assembly into a common nuclear protein complex. This gene encodes the protein for complementation group D2. This protein is monoubiquinated in response to DNA damage, resulting in its localization to nuclear foci with other proteins (BRCA1 AND BRCA2) involved in homology-directed DNA repair. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 815 of the FANCD2 protein (p.Arg815Gln). This variant is present in population databases (rs766567785, gnomAD 0.05%). This missense change has been observed in individual(s) with Fanconi anemia (PMID: 17436244, 27041517). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 241735). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt FANCD2 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: FANCD2 c.2444G>A (p.Arg815Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00013 in 251202 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in FANCD2 causing Fanconi Anemia (0.00013 vs 0.00048), allowing no conclusion about variant significance. c.2444G>A has been reported in the literature in multiple homozygous and compound heterozygous individuals affected with Fanconi Anemia and was shown to segregate with disease within at least one family (Kalb_2007, Esmail Nia_2016). These data indicate that the variant is very likely to be associated with disease. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

Collection Method: clinical testing

The FANCD2 c.2444G>A variant is predicted to result in the amino acid substitution p.Arg815Gln. This variant has been reported in the homozygous or compound heterozygous state in several patients with Fanconi anemia (Kalb et al 2007. PubMed ID: 17436244; Esmail et al. 2016. PubMed ID: 27041517; Deniskin et al. 2018. PubMed ID: 30713837). This variant has also been reported along with a second variant in FANCD2 in two individuals with osteosarcoma (eTable 5, Mirabello et al. 2020. PubMed ID: 32191290). This variant is reported in 0.058% of alleles in individuals of Latino descent in gnomAD. This variant is interpreted as pathogenic. -
