Tsuchida et al., observed a potential relationship between FUCA1 expression and p53 status, with a decreased expression of FUCA1 and the presence of mutated p53 in ATCs, and an increased expression of FUCA1 in PTCs, which predominantly harbor wild-type p53 (99). The gene discussed is TP53; the disease is Ehlers-Danlos syndrome, musculocontractural type.
