Genes affected
FANCC (HGNC:3584): (FA complementation group C) 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 C. [provided by RefSeq, Jul 2008]
AOPEP (HGNC:1361): (aminopeptidase O (putative)) This gene encodes a member of the M1 zinc aminopeptidase family. The encoded protein is a zinc-dependent metallopeptidase that catalyzes the removal of an amino acid from the amino terminus of a protein or peptide. This protein may play a role in the generation of angiotensin IV. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2010]

Benign, criteria provided, single submitterclinical testingGeneDxJan 07, 2014This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Fanconi anemia complementation group C Benign:1
Likely benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This 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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
not provided Benign:1
Likely benign, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The FANCC p.Thr469= variant was not identified in the literature nor was it identified in the COSMIC, MutDB, or LOVD 3.0 databases. The variant was identified in dbSNP (ID: rs79722116) as “With Benign allele”, and in the ClinVar and Clinvitae databases (classified as benign by GeneDx and Invitae; and likely benign by Ambry Genetics). The variant was identified in control databases in 122 of 277068 chromosomes (1 homozygous) at a frequency of 0.0004 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: “Other” in 2 of 6452 chromosomes (freq: 0.0003), Latino in 1 of 34416 chromosomes (freq: 0.00003), European Non-Finnish in 3 of 126610 chromosomes (freq: 0.00002), East Asian in 111 of 18864 chromosomes (freq: 0.006), Finnish in 1 of 25776 chromosomes (freq: 0.00004), and South Asian in 4 of 30774 chromosomes (freq: 0.0001); it was not observed in the African or Ashkenazi Jewish, populations. The p.Thr469= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2017This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
