Nonmedullary thyroid cancer (NMTC) comprises cancer of follicular cell origin and accounts for more than 95% of all cases of thyroid cancer. Familial NMTC accounts for 3 to 9% of all cases of thyroid cancer and has an autosomal dominant mode of inheritance. Most cases of familial NMTC are papillary thyroid cancer (PTC), which is the most common type of thyroid cancer (summary by Gara et al., 2015).
For a general phenotypic description and a discussion of genetic heterogeneity of NMTC, see NMTC1 (188550). [from
