Genes affected
FANCG (HGNC:3588): (FA complementation group G) 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 G. [provided by RefSeq, Jul 2008]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Glu395Trpfs*5) in the FANCG gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FANCG are known to be pathogenic (PMID: 12552564). This variant is present in population databases (rs397507559, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with Fanconi anemia (PMID: 11093276, 24584348). ClinVar contains an entry for this variant (Variation ID: 41224). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic.
