Genes affected

FANCI (HGNC:25568): (FA complementation group I) 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 I. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest MAF: 0.5% [190/41448] and 1 homozygote, https://gnomad.broadinstitute.org/variant/15-89300313-G-T?dataset=gnomad_r3). This variant is present in ClinVar, with multiple laboratories classifying it as benign (Variation ID:456210). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant suggests that this variant does not cause disease but requires further evidence. Therefore, this variant is classified as likely benign. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: FANCI c.2817G>T (p.Lys939Asn) results in a non-conservative amino acid change located in the FANCI solenoid 3 domain (IPR029313) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00035 in 251414 control chromosomes, predominantly at a frequency of 0.0039 within the African or African-American subpopulation in the gnomAD database, including 1 homozygote. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 14 fold of the estimated maximal expected allele frequency for a pathogenic variant in FANCI causing Fanconi anemia phenotype (0.00028), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.2817G>T in individuals affected with Fanconi anemia, complementation group I and no experimental evidence demonstrating its impact on protein function have been reported. One ClinVar submitter (evaluation after 2014) cites the variant as benign. Based on the evidence outlined above, the variant was classified as benign. -
