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]

Likely pathogenic, criteria provided, single submitter	clinical testing	Fulgent Genetics, Fulgent Genetics	Nov 22, 2021	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 02, 2024	This sequence change falls in intron 5 of the FANCE gene. It does not directly change the encoded amino acid sequence of the FANCE protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individuals with Fanconi anemia (PMID: 10205272, 35295078; Invitae). ClinVar contains an entry for this variant (Variation ID: 8711). Studies have shown that this variant results in activation of cryptic splice site and introduces a premature termination codon (PMID: 11001585). The resulting mRNA is expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic. -
