GeneDx RCV000481574 SCV000566398 uncertain significance not provided 2017-06-08 criteria provided, single submitter clinical testing This variant is denoted FANCC c.233C>A at the cDNA level, p.Pro78His (P78H) at the protein level, and results in the change of a Proline to a Histidine (CCT>CAT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. FANCC Pro78His was not observed at a significant allele frequency in large population cohorts (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek 2016). Since Proline and Histidine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. FANCC Pro78His occurs at a position that is conserved across species and is located in the region of interaction with RED (Gordon & Buchwald 2000). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available information, it is unclear whether FANCC Pro78His is pathogenic or benign. We consider it to be a variant of uncertain significance.
Invitae RCV000531726 SCV000626242 uncertain significance Fanconi anemia 2019-04-11 criteria provided, single submitter clinical testing This sequence change replaces proline with histidine at codon 78 of the FANCC protein (p.Pro78His). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and histidine. This variant is present in population databases (rs138722298, ExAC 0.02%). This variant has not been reported in the literature in individuals with FANCC-related disease. ClinVar contains an entry for this variant (Variation ID: 418955). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
