Whole exome data from 59 participants from 20 kindreds were examined for mutations in HABP2 and the thyroid cancer susceptibility genes SRGAP1, NKX2-1, SRRM2 and FOXE1. The population prevalence of the G534E variant in HABP2 was examined in two independent cohorts. The gene discussed is FOXE1; the disease is thyroid gland carcinoma.
