Genes affected

FANCF (HGNC:3587): (FA complementation group F) 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 F. [provided by RefSeq, Jul 2008]

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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

BA1, BS2, BP4_Moderate c.557C>T, located in exon 1 of the FANCF gene, is predicted to result in the substitution of alanine by valine at codon 86, p.(Ala186Val). The variant allele was found in 514/30518 alleles, with a filtering allele frequency of 1.5% at 99% confidence, within the South Asian population in the gnomAD v2.1.1 database (non-cancer data set) (BA1). The SpliceAI algorithm predicts no significant impact on splicing. The REVEL meta-predictor score for this variant (0.041) suggests that it does not affect the protein function according to Pejaver 2022 thresholds (PMID: 36413997) (BP4_Moderate). To our knowledge, neither relevant clinical data nor well-established functional studies have been reported for this variant. This variant has been observed in homozygous state in multiple healthy individuals (BS2). This variant has been reported in the ClinVar database (6x benign, 3x likely benign) and in LOVD (1x benign). Based on currently available information, the variant c.557C>T should be considered a benign variant, according to ACMG/AMP classification guidelines. -
