This variant is denoted FANCC c.271A>G at the cDNA level, p.Ile91Val (I91V) at the protein level, and results in the change of an Isoleucine to a Valine (ATA>GTA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. FANCC Ile91Val was not observed at a significant frequency in large population cohorts (Lek 2016, The 1000 Genomes Consortium 2015, NHLBI Exome Sequencing Project). Since Isoleucine and Valine share similar properties, this is considered a conservative amino acid substitution. FANCC Ile91Val occurs at a position that is not conserved and is located within the region that interacts with RED (Gordon 2000). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether FANCC Ile91Val is pathogenic or benign. We consider it to be a variant of uncertain significance.
