On the genetic level, direct sequencing of the complete coding sequences of FANCC, FANCF and FANCG in 18 HCC samples identified a single not previously reported, heterozygous, synonymous FANCC sequence variant (c.813G > A) and two heterozygous, non-synonymous FANCG variants (c.20C > T, p.S7F; c.643C > A, p.Q215K) (Fig. 6A). Here, FANCG is linked to hepatocellular carcinoma.
