Comment:

The c.165+2_165+3insTT intronic variant, results from an insertion of two nucleotides at nucleotide position 165 after intron 1 of the FANCC gene. This nucleotide position is highly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to abolish the native splice donor site; however, direct evidence is unavailable. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
