The c.35G > A (p.Gly12Asp) mutation in KRAS was in all three samples present in a heterozygous state (Figure 4), with an average allele frequency of 44% in the hyperpigmented verrucous skin sample, 49% in the tumor sample with the concentric intraneural Schwann cell proliferation and 56% in the lipoma sample based on peak height of both nucleotides at position 35. Here, KRAS is linked to lipoma.
