Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_000136.3(FANCC):āc.34T>Gā(p.Tyr12Asp) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,842 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y12C) has been classified as Uncertain significance.

Submissions by phenotype
Fanconi anemia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 13, 2021 | This sequence change replaces tyrosine with aspartic acid at codon 12 of the FANCC protein (p.Tyr12Asp). The tyrosine residue is moderately conserved and there is a large physicochemical difference between tyrosine and aspartic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with FANCC-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 22, 2019 | The p.Y12D variant (also known as c.34T>G), located in coding exon 1 of the FANCC gene, results from a T to G substitution at nucleotide position 34. The tyrosine at codon 12 is replaced by aspartic acid, an amino acid with highly dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
