GeneDx RCV000485462 SCV000570707 uncertain significance not provided 2016-06-20 criteria provided, single submitter clinical testing This variant is denoted FANCC c.934A>C at the cDNA level, p.Ile312Leu (I312L) at the protein level, and results in the change of an Isoleucine to a Leucine (ATA>CTA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. FANCC Ile312Leu was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Isoleucine and Leucine share similar properties, this is considered a conservative amino acid substitution. FANCC Ile312Leu occurs at a position that is not conserved and is located in the region of interaction with Hsp70 (Gordon 2000). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether FANCC Ile312Leu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
