Genes affected

FANCE (HGNC:3586): (FA complementation group E) 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 E. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Val311Serfs*2) in the FANCE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FANCE are known to be pathogenic (PMID: 11001585, 17924555). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with esophageal and breast cancer (PMID: 21279724, 26822949). ClinVar contains an entry for this variant (Variation ID: 655390). For these reasons, this variant has been classified as Pathogenic. -
