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]
GAS2 (HGNC:4167): (growth arrest specific 2) The protein encoded by this gene is a caspase-3 substrate that plays a role in regulating microfilament and cell shape changes during apoptosis. It can also modulate cell susceptibility to p53-dependent apoptosis by inhibiting calpain activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2017]

Fanconi anemia Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 07, 2023This premature translational stop signal has been observed in individual(s) with Fanconi-anemia (PMID: 10615118). This variant is also known as 23 bp nt. 230-252. ClinVar contains an entry for this variant (Variation ID: 6340). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects FANCF function (PMID: 10615118). This variant disrupts a region of the FANCF protein in which other variant(s) (Leu162Aspfs*103) have been determined to be pathogenic (PMID: 10615118, 26033879, 27714961, 28102861). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. This variant is present in population databases (rs730880277, gnomAD 0.01%). This sequence change creates a premature translational stop signal (p.Val77Glyfs*6) in the FANCF gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 298 amino acid(s) of the FANCF protein. -
